Things to Do in Kauai: 35 Experiences Ranked and Rated Honestly

Kauai has fewer must-dos than Oahu or Maui, but more that are worth planning your whole trip around. This guide ranks all 35 of them, tells you what each one costs and how long it takes, and says plainly which ones to skip.

Below you will find the full ranked table, then every experience grouped by region so you can turn the list into days. Prices for guided tours are the current rates listed on our tour pages; park fees and reservation rules are those published by Hawaiʻi State Parks and the operators at the time of writing.

How we ranked these 35 Kauai experiences

Most “things to do in Kauai” articles are one traveler’s trip report. That is useful, but it is one opinion. We ranked these 35 experiences on three public criteria so you can see why each one sits where it does:

1. Consensus. How many of the seven most-read Kauai guides on Google include it. An experience that appears in 6 or 7 of them is a safe bet; one that appears in 1 or 2 is a personal favorite.
2. What reviewers say. For guided tours listed on tripreviewall.com, we read both the 5-star and the 1-star reviews across booking platforms. The complaints matter more than the praise, because they tell you who should not book.
3. Effort and cost. Free and under 30 minutes beats expensive and all-day when the payoff is similar.

We do not accept payment from operators to appear in this list. Some links go to tour pages on our site that earn us a commission if you book; that never changes the ranking.

Kauai at a glance: all 35 experiences in one table

Costs are per adult at the time of writing. Hāʻena and Kōkeʻe/Waimea fees apply to non-residents.

If you only have time for five

1. Na Pali Coast by boat (or by helicopter if anyone in your group gets seasick).
2. Waimea Canyon and the Kalalau Lookout, in the morning before the clouds come in.
3. Keʻē Beach and the first two miles of the Kalalau Trail, with a Hāʻena reservation.
4. Kayak the Wailua River to Secret Falls.
5. Sunset at Hanalei Bay, ideally from the pier.

Those five cover the island’s four regions and three kinds of day: on the water, on a trail, and on the sand.

The Na Pali Coast: boat, helicopter or hike?

Every Kauai guide agrees the Na Pali Coast is the island’s single best sight. The 17 miles of 3,000-foot cliffs on the northwest shore have no road, so you choose how to see them. The honest answer is that the best way depends on your stomach, your budget and who is with you, not on which one is “best” in the abstract.

1. A Na Pali boat tour is the best value on the island

Boats leave from Port Allen or Kikiaola (west side) year-round and from Hanalei (north shore) in summer. The two formats are very different:

• Rigid-hull rafts (Zodiacs) get into the sea caves and under waterfalls, and are the cheapest way onto the coast. The Na Pali Riders sea caves and snorkel expedition from Kekaha starts at $129. Reviews praise the cave access and the captains; the recurring complaint is the ride itself, which is wet, bumpy and hard on backs, with no shade or toilet.
• Catamarans are slower and far more comfortable, with shade, a bathroom, lunch and drinks. Holo Holo Charters runs the Napali Coast snorkel excursion from Port Allen for $235 and the longer Niʻihau and Napali expedition for $295, which adds a snorkel stop at the “Forbidden Island.” The Niʻihau route means more time in open ocean, so take the seasickness advice seriously.
• From Hanalei, the Napali Snorkel Adventure ($299) puts you on the coast within minutes of leaving the pier, but it only runs when the north shore is calm, roughly May to September.

Read the 1-star reviews before you choose: almost all of them are about seasickness or a weather cancellation, not about the crew or the scenery. Take motion-sickness medication the night before, eat a light breakfast, and sit at the back of the boat.

2. A doors-off helicopter shows you the whole island in an hour

Seven out of seven top guides include a helicopter flight, and most of them call it the highlight of the trip. From Lihue you cross the island’s interior, hover at Manawaiopuna Falls (the “Jurassic Park” waterfall), fly the length of the Na Pali cliffs, then turn through Waimea Canyon on the way back.

Jack Harter Helicopters flies doors-off MD500s for a 60–65 minute tour from $364. With no glass between you and the cliffs, photos are sharper and the experience is far more intense. Expect to be cold and windblown; secure hats, glasses and phones. Seats are assigned by weight, not by request, which is the most common reviewer complaint. Aliʻi Air runs private 50–60 minute tours from $389 if you want the cabin to yourselves.

Book the earliest flight you can. Morning air is calmer and clearer, and if weather cancels your slot you still have the rest of your trip to rebook.

3. The Kalalau Trail to Hanakapiʻai is the hike everyone wants

The Kalalau Trail runs 11 miles along the Na Pali Coast, but most people hike only the first section. You do not need a permit to hike 2 miles to Hanakapiʻai Beach or to continue 2 more miles up the valley to 300-foot Hanakapiʻai Falls. The permit requirement, and the serious hiking, begins after you cross Hanakapiʻai Stream and head toward Kalalau.

What you do need is a Hāʻena State Park reservation (see #5), because the trailhead is inside the park. The trail is muddy and slippery most of the year, the beach is not safe for swimming, and the stream crossings can become impassable after rain. Plan 3 hours for the beach and 6–7 hours for the falls. Bring more water than you think you need.

If you want the full overnight experience, read our guide to Kalalau Trail permits first. Permits are released 90 days ahead and sell out within minutes.

North Shore: Hanalei, Hāʻena and the beaches you must reserve

The north shore is the Kauai of postcards: taro fields, one-lane bridges, a half-moon bay and the start of the Na Pali cliffs. It is also the wettest part of the island and the one with the most rules, because the road ends here and parking is scarce. Winter surf closes most of the beaches to swimming from November through March.

4. Hanalei Bay is the one place every guide agrees on

Hanalei is the only item that appears in all seven top guides. The two-mile crescent bay is calm enough for swimming and beginner surf lessons in summer, and the pier is the island’s best free sunset spot. The town itself is three blocks of surf shops, food trucks and shave ice. Spend an afternoon here, then come back for sunset on a different night.

On Saturday mornings the Waipā farmers market, just west of town, is worth a stop for fruit and poi. Stop at the Hanalei Valley Lookout on the drive in; the view over the taro fields takes five minutes and costs nothing.

5. Keʻē Beach needs a reservation, and it is worth the trouble

Keʻē Beach sits at the very end of the road inside Hāʻena State Park, with a protected lagoon that is one of the island’s best beginner snorkel spots in summer. The trailhead for the Kalalau Trail is a few steps from the parking lot.

Non-residents must reserve in advance at gohaena.com. Reservations open 30 days ahead at midnight Hawaiʻi time and sell out quickly. You have three choices:

• Park and entry: $10 per vehicle plus $5 per person, in timed slots.
• Shuttle from Waipā: about $40 per person including entry, the only option if parking is gone.
• Entry only: $5 per person if someone drops you off or you walk or bike in.

Parking outside the park on the road is ticketed and towed, so do not try it. For a full walkthrough of the system, read our Keʻē Beach guide.

6. Tunnels Beach has the best snorkeling, in summer only

Tunnels (Mākua) Beach is a long reef with lava tubes and ledges that holds turtles, parrotfish and the occasional reef shark. In winter the same reef produces the waves that make the north shore famous, and the beach becomes a surf spot only. Go between May and September, in the morning, when the water is clearest.

There is almost no parking at Tunnels itself. Park at Hāʻena Beach Park a short walk east, which has restrooms and lifeguards, or come by shuttle. Tunnels needs no reservation. See our Tunnels Beach guide for entry points and conditions.

11. Anini Beach is the safe north-shore swim

Anini has the longest fringing reef in Hawaiʻi, which keeps the water flat even when the rest of the north shore is closed. It is shallow, so snorkeling is best at high tide, and it is the north shore’s easiest beach for small children. There is free parking along the beach road, restrooms and shade.

15. Kilauea Point Lighthouse is an hour well spent

The 1913 lighthouse sits on the northernmost point of the main islands, inside a national wildlife refuge. You come for the birds: red-footed boobies, frigatebirds, nēnē, and from November to July, Laysan albatross. Humpback whales pass below in winter. Entry is $10 per adult with timed reservations through recreation.gov; the refuge is closed on Sunday and Monday. Plan an hour.

19. Hideaways and Puʻu Poa are Princeville’s hidden beaches

Below the Princeville resorts, two small beaches reward a short effort. Puʻu Poa is reached through the St. Regis grounds and has good reef snorkeling in summer. Hideaways is down a steep, rooty path with a rope rail; it is tiny, sheltered and beautiful, and not a place for children or anyone unsteady on their feet. Parking is a handful of public spots at the top of the path.

20. Limahuli Garden shows you what Kauai looked like before hotels

Limahuli, in Hāʻena, is a National Tropical Botanical Garden built around ancient taro terraces in a valley that frames the Na Pali cliffs. The self-guided loop takes about 90 minutes and costs around $30; reservations are required. Of the five gardens on the island, this is the one to pick if you want landscape and Hawaiian history rather than plant collections.

35. Queen’s Bath is the most dangerous “attraction” on the island

Queen’s Bath, a lava-rock tide pool in Princeville, appears in four of the seven top guides, and that is a problem. People have died here when swells washed them off the ledge; the county keeps a tally on a sign at the trailhead. The pool is only safe in summer on flat-calm days, and even then the trail down is a mud slide. If the surf forecast shows anything over 3 feet on the north shore, do not go. We rank it last for a reason.

East Side: Wailua River, waterfalls and Kapaa

The east side is where most flights land, where the only navigable river in Hawaiʻi reaches the sea, and where you will spend time in traffic. Kapaa is the island’s biggest town and a sensible base for first-timers because every region is within a 45-minute drive.

9. Kayak the Wailua River to Secret Falls

This is the east side’s one must-do. You paddle about two miles up the flat, slow Wailua River, tie up, then hike a muddy mile through forest to Uluwehi (Secret) Falls, a 100-foot waterfall with a swimming pool at its base. The whole trip takes 4–5 hours and is easy for anyone who can sit in a kayak.

Guided tours (around $100–$130) include the kayak, dry bags, lunch and a guide who knows the river crossings; rentals are cheaper but you navigate yourself and tours are not allowed on Sundays. After heavy rain the stream crossing on the hike can be unsafe, so check conditions. Our Wailua River kayak guide compares the operators.

13. Wailua Falls is a ten-minute stop, and that is fine

The 80-foot double waterfall from the opening credits of Fantasy Island is at the end of Māʻalo Road, a 15-minute drive from Lihue. You look at it from a roadside viewpoint, take your photos and leave. The old trail down to the pool is closed and dangerous. Go after rain when both channels flow, and combine it with Ōpaekaʻa Falls, another roadside lookout 15 minutes away above the Wailua River.

14. Sleeping Giant is the best short hike on the east side

The Nounou Ridge looks like a man lying on his back, and the East Trail climbs to his chest in about 1.75 miles. Expect switchbacks, a few rocky scrambles near the top and a 360-degree view from the coast to Mount Waiʻaleʻale. It takes 2–3 hours round trip. Start before 8 am; the trail is exposed and hot by mid-morning. The trailhead on Haleilio Road has a small free lot.

24. Kipu Ranch ATV is the island’s best rainy-day plan

Kipu Ranch is a working cattle ranch between Lihue and Poipu that doubled as a film set for Jurassic Park, Raiders of the Lost Ark and The Descendants. Kipu Ranch Adventures runs the Waterfall Trail Expedition, a 2.5–3 hour ATV tour ending at a swimming hole, from $50 per person. Reviewers love the movie locations and the mud; the point of an ATV tour is that rain makes it better, not worse. Children can ride as passengers from age 5. Compare Kipu Ranch’s tours and reviews on our Kauai ATV tours page.

25. A guided waterfall hike gets you to pools you cannot find alone

Da Life Outdoors (Kauai Beach Boys) runs a 2–3 hour Waterfall Swim and Hike from Lihue for $69, on private land near Kipu, so you will not share the pool with a tour bus. The same company offers a waterfall rappel for the adventurous and a one-hour outrigger canoe paddle for $69 if you would rather see the river the traditional way.

26. Hoʻopiʻi Falls is the local waterfall hike

In the Kapahi neighborhood above Kapaa, an unmarked trail follows Kapaʻa Stream to two waterfalls (the second was used in the opening of Jurassic Park). It is 1.5–2 hours round trip, slick after rain, and the trailhead is in a residential street with room for a few cars. Park considerately and keep your voice down; the neighbors have asked.

27. Ride the Kapaa bike path at sunrise

Ke Ala Hele Makalae is an eight-mile paved path along the east shore from Lydgate to Kealia Beach and beyond. Rent a cruiser in Kapaa ($20–$40) and ride north past Kealia for an hour, or walk any part of it. Whales are visible from the path in winter.

34. Lydgate Beach Park is where to bring small children

Two rock-walled ocean pools keep the waves out, so toddlers can float safely while fish swim in. There are lifeguards, showers, a huge wooden playground and plenty of parking. It is five minutes from the airport, which makes it a good first or last stop.

South Shore: Poipu, Mahaulepu and the quick stops

The south shore is the sunny, dry side, with the island’s biggest resorts and most reliable beach weather. It is the best base in winter, when the north shore is rainy and unswimmable.

10. Poipu Beach is the island’s best all-round beach

Poipu Beach Park has a sand tombolo that splits the bay in two: a sheltered pool for children on one side and a snorkel reef with turtles on the other. Hawaiian monk seals haul out here most weeks; stay behind the rope volunteers set up. There are lifeguards, restrooms and showers, and the parking lot fills by 10 am. For nearby beaches and snorkel spots, see things to do in Poipu.

17. The Mahaulepu Heritage Trail is the easiest great walk on Kauai

From Shipwreck Beach, this coastal trail runs about two miles east over lithified sand dunes, past blowholes, sea arches and a cove of its own, with no road and no buildings. It is flat, free and uncrowded. Go in the morning before the trade winds pick up; there is no shade. Turn back whenever you like.

18. Shipwreck Beach is for watching, not swimming

The beach below the Grand Hyatt is known for its cliff jumpers, who leap from the 35-foot rock at the east end. The shorebreak is heavy and the current strong, so most visitors sunbathe, watch the surfers and start the Mahaulepu trail from here. Public parking is at the end of Ainako Street.

21. Allerton and McBryde Gardens are the south shore’s big-ticket gardens

Both belong to the National Tropical Botanical Garden in Lāwaʻi Valley. McBryde is a self-guided tram-and-walk visit (around $30) with the world’s largest collection of native Hawaiian plants. Allerton is a guided 2.5-hour tour (around $60) through a landscaped estate garden with the Moreton Bay fig roots from Jurassic Park. Pick one, not both, and reserve.

22. A luau is worth one night if you choose the right one

Two of seven guides include a luau, and the split is honest: a luau is expensive ($130–$200 per adult) and some are tourist-factory buffets. On Kauai the two that reviewers consistently rate highest are the Smith Family Garden Luau in Wailua, set in a 30-acre garden with an imu ceremony, and Luau Kalamaku at Kilohana Plantation, which is more theatrical. Our best luau in Kauai guide compares food, seating and what the 1-star reviews complain about.

23. Koloa Landing is one of the best shore dives in Hawaiʻi

Koloa Landing is a protected cove with turtles, frogfish and easy entry, which is why every Kauai dive shop runs beginner dives here. Fathom Five’s 1-Tank Discover SCUBA at Koloa Landing is $150 and takes 2–3 hours with no certification needed (ages 10 and up). Certified divers can take their 2-tank boat dive to the south-shore reefs. Compare the dive operators on our Kauai scuba page.

33. Spouting Horn takes fifteen minutes

A lava tube on the Poipu coast turns incoming waves into a geyser up to 50 feet high, with a moaning sound from a second hole. Visit at high tide with a big south swell, park in the free lot, take your photo and move on. It is a pleasant stop on the way to the gardens, not a destination.

West Side: Waimea Canyon, Kōkeʻe and Polihale

The west side is dry, red and empty. The drive from Hanalei takes about two hours, so most visitors give the west side one full day: canyon in the morning, a Kōkeʻe hike or Polihale in the afternoon, Hanapepe or a Port Allen sunset sail on the way back.

7. Waimea Canyon earns the Grand Canyon comparison

Ten miles long and up to 3,000 feet deep, Waimea Canyon is red rock streaked with green and cut by waterfalls. Drive Waimea Canyon Drive (Route 550) and stop at the Waimea Canyon Lookout at mile 10, then the Puʻu Hinahina Lookout at mile 13. Non-residents pay $5 per person plus $10 per vehicle at the lookouts; one payment covers Waimea Canyon and Kōkeʻe state parks for the day.

Go before 10 am. By midday clouds fill the upper canyon and the lookouts can show nothing but white. Our Waimea Canyon guide lists every lookout with mile markers.

8. Kalalau Lookout is the view you cannot get any other way

Keep driving past Kōkeʻe Lodge to the end of the road. At 4,000 feet, the Kalalau Lookout and Puʻu o Kila Lookout face straight down the Kalalau Valley to the ocean, the same cliffs you see from a Na Pali boat, from the top. Clouds often cover the view; if they do, wait 15 minutes, as they usually blow through. Mornings are clearest.

16. Awaʻawapuhi Trail ends on a knife-edge above the Na Pali Coast

The best day hike in Kōkeʻe drops 1,600 feet over 3.1 miles through forest to a ridge with cliffs falling away on both sides into the Awaʻawapuhi and Nuʻalolo valleys. The way back is all uphill, so allow 3–4 hours and carry water. Start early; the ridge clouds over after noon. Not for small children or anyone nervous about heights. See our best hikes in Kauai for alternatives such as the Pihea Trail.

29. Waipoʻo Falls is the hike inside the canyon

From the Puʻu Hinahina area, the Canyon Trail descends to the top of 800-foot Waipoʻo Falls in about 1.8 miles, with views back across the canyon the whole way. You stand at the top of the falls and in the small pools above them, not at the bottom. It is 2–3 hours round trip, red-dirt slippery when wet.

28. Kauai Coffee is the free stop; farm tours are the paid one

Kauai Coffee in Kalaheo is the largest coffee farm in the United States, and its self-guided walk and tasting room are free. For something more hands-on, Common Ground in Kilauea runs a two-hour Farm and Food Experience for $145 that ends with a tasting menu grown on the property. Four of seven guides mention coffee; the farm tour is for travelers who want to eat, not just sip.

30. Polihale is the end of the road, literally

Polihale State Park is 17 miles of empty sand at the far west end of the island, where the Na Pali cliffs begin, reached by five miles of rutted dirt road. Rental-car contracts often forbid it, and two-wheel-drive cars get stuck. The surf is dangerous year-round; this is a sunset-and-walk beach, not a swimming beach. If you go, bring everything, including water and shade.

31. Hanapepe is the island’s art town

“Kauai’s biggest little town” has a swinging footbridge, a dozen galleries and bookstores in plantation-era storefronts, and the Friday Art Night from 5 to 8 pm with food trucks and live music. It also inspired the town in Lilo & Stitch. Give it an hour, or a Friday evening.

32. Salt Pond Beach Park is the west side’s calm swim

Salt Pond, just west of Hanapepe, is a crescent of sand protected by a reef, with lifeguards and shallow, usually calm water. Local families still harvest sea salt from the ponds behind the beach, which is why it has the name. No guide in our top seven mentions it, which is exactly why it is uncrowded.

Adventure tours worth the money, and the rainy-day plan

Kauai’s paid adventures are good value compared with Oahu and Maui, but not all of them are worth a slot in a one-week trip. Here is how they rank.

• Whale watching (December–April). Humpbacks arrive in December and peak in February and March. West-side and south-shore boats run 2–3 hour whale cruises ($120–$210), and the Na Pali boats double as whale tours in winter. You can also see them for free from Kilauea Point and the Kapaa bike path. Read whale watching in Kauai for the season week by week.
• Mountain tubing. Kauai Backcountry Adventures floats you through old sugar-plantation irrigation ditches and tunnels in inner tubes for about three hours. It is gentle, fun for families with children over five, and unique to Kauai. Book ahead; it sells out.
• Ziplining. Several courses on the east and south sides; the longest lines are at Kōloa Zipline and Kauai Backcountry. Compare in ziplining in Kauai.
• Surf lessons. Hanalei Bay in summer and Poipu year-round have the gentlest waves for beginners.
• Sunset sail. Holo Holo Charters’ Kauai sunset sails from Port Allen start at $210 and run 2–3 hours along the south and west coasts with drinks and appetizers; in winter they often turn into whale watches.

Overrated, dangerous, or just a ten-minute stop

The Honest Guide ranks down as well as up. These experiences appear in many top guides and deserve a warning.

• Queen’s Bath (#35). Dangerous from October to April and after any big swell. Deaths are regular. Go only on a flat summer day.
• Fern Grotto boat tour. A slow, narrated barge ride up the Wailua River to a fern-draped cave you view from a platform. Pleasant for grandparents; dull for everyone else. Kayak the same river instead (#9).
• Spouting Horn and Wailua Falls (#33, #13). Both are worth seeing, but they are 15-minute roadside stops, not half-day plans. Combine them with the gardens and Poipu, or with Ōpaekaʻa Falls.
• Hanakapiʻai Beach swimming. Many hikers try. The beach has no reef and a brutal rip current, and more than 80 people have drowned here. Hike to it, do not swim at it.
• Golf. Four of seven guides mention it, mostly because of Princeville and Poipu Bay. If you are not already a golfer, skip it.

Before you go: six things the guides agree on

1. Reserve three things early. Hāʻena State Park (30 days ahead, gohaena.com), helicopter and Na Pali boat tours (2–4 weeks in high season), and Kalalau camping permits if you want them (90 days ahead).
2. Each side has its own weather. The north shore can be raining while Poipu is sunny. Weather apps show “rain” for the whole island almost every day; look at the hourly forecast for the exact town instead, and if it rains where you are, drive 30 minutes.
3. Drive times are longer than they look. Lihue to Hanalei is about an hour, Lihue to Waimea Canyon about 1.5 hours, Hanalei to Waimea about 2 hours, and the two ends of the road do not connect. Kapaa traffic is slow at 7–9 am and 3–6 pm.
4. Winter changes the north shore completely. From November to March, Tunnels, Keʻē and Hanalei can be unswimmable, and north-shore boat tours stop. Base in Poipu in winter and in Hanalei or Kapaa in summer. See north shore vs south shore.
5. Bring reef-safe sunscreen. Hawaiʻi bans sunscreens with oxybenzone and octinoxate. Mineral sunscreen is the safe choice and is sold everywhere on the island.
6. The chickens are not a tourist attraction. Wild chickens are everywhere, including at 4,000 feet in Kōkeʻe. Do not feed them, and expect roosters at 4 am wherever you stay.
