About the Operator in General
Coral Reef Snorkel Adventures runs three Kona trips on Greetwell: this Kealakekua Bay tour from $106, a small-group raft reef snorkel from $134 and a manta ray night snorkel from $134; HawaiiGuide gives the operator its highest 91/100 provider score for the manta and Kealakekua trips.
Our Verdict
Tripreviewall's Take
For $106 this is a comparatively cheap way to reach the Captain Cook Monument reef, which most Kona boat tours charge $130 to $180 to visit, and the operator's 4.8 rating from 397 reviews plus its small-group format make it a sound choice for families. The missing basics are the problem: we could not confirm the duration, departure time, what gear is provided or the refund policy. Get those on the FareHarbor page before you pay.
Book This Tour If…
You want to snorkel the Captain Cook Monument reef without hiking the steep trail
You prefer a small boat with a guide in the water to a 100-passenger catamaran
You have children or non-native English speakers in the group; the review we read praised the crew's patience
You are on a budget; $106 is the lowest price we found for a guided Kealakekua Bay boat trip
Skip This Tour If…
You need shade, a restroom, lunch and a waterslide; the big Kona catamarans offer those
You want a confirmed duration and departure time before booking; none was published
You are prone to seasickness on small boats
You want to see manta rays; that is the operator's separate night trip

Frequently Asked Questions
How much is the Coral Reef Snorkel Adventures Kealakekua Bay tour?
The Coral Reef Snorkel Adventures Captain Cook Monument Snorkel Tour in Kealakekua Bay was listed from $106 per person on Greetwell in October 2026, making it the cheapest of the operator's three Kona trips. The same operator's small-group raft reef snorkel and manta ray night snorkel were each listed from $134.
Why do people snorkel at the Captain Cook Monument?
The Captain Cook Monument marks the Kealakekua Bay shoreline where the reef is protected as a marine life conservation district, so coral and fish are healthier than at open-access beaches. The spot has no road access, so visitors arrive by boat tour, permitted kayak or a steep roughly 2-mile trail each way, which is why guided boat trips exist.
Is Coral Reef Snorkel Adventures a small-group operator?
Yes, Coral Reef Snorkel Adventures describes its Kona trips as intimate small-group excursions, and Greetwell's summary of the operator's 397 reviews lists small group size as a recurring strength.
