Sail & Snorkel Kealakekua Bay: Captain Cook Monument Catamaran Cruise
Set sail from Keauhou Bay for a half-day catamaran cruise to the Captain Cook Monument and Kealakekua Bay’s protected reef. Expect calm morning sails, two snorkel stops, and abundant marine life—including spinner dolphins and sea turtles—in one of Hawaii’s clearest coves.
The Experience
Before You Go
Arrive early for check-in
Check in at 8:15 a.m. at Keauhou Bay’s finger pier—parking fills fast and boarding begins about 15 minutes before departure.
Respect the marine sanctuary
Do not touch coral or feed wildlife; anchors and fishing are restricted around the monument to protect reef habitat.
Prepare for motion
Take seasickness medication before boarding if you’re prone to motion sickness—morning swells are usually mild but conditions change.
Bring a waterproof camera
Underwater photos are the highlight—bring a decent dive mask and a waterproof camera or housing for best shots.

Kealakekua Bay is a designated marine sanctuary—fishing and touching coral are restricted, and operators emphasize reef-safe sunscreen and no-contact practices to protect the ecosystem.
