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.

Local Knowledge

Hidden Gems

  • Look back toward the Kona coastline from the south for layered lava terraces and private coves.
  • If conditions allow, the second snorkel at Red Hill has quieter reef sections with different fish species.

Wildlife

  • Spinner dolphins
  • Hawaiian green sea turtles

Conservation Note

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.

The Captain Cook Monument marks the spot where Captain James Cook was killed in 1779; the bay was also a site of traditional Hawaiian ritual and settlement.
