The Experience
Before You Go
Arrive Early
Check in 30 minutes before departure at the picnic tables right of the docks to allow time for gear fit and briefing.
Take Motion-Sickness Prep
Transit to Kanaio can be choppy; take antiemetic medication in advance if you’re susceptible.
Use Reef-Safe Sunscreen
Bring biodegradable, reef-safe SPF and a rash guard to protect both skin and coral.
Waterproof Camera or Case
Caves and Molokini deliver the best shots — protect your phone or camera for submerged and splash-prone moments.
Local Knowledge
Hidden Gems

- •The La Perouse coastal trail (on land) offers stark lava formations and fewer visitors if you have time before/after the tour

Conservation Note
Reefs here are fragile; use reef-safe sunscreen, avoid touching coral or turtles, and follow guides’ low-impact protocols.
La Perouse Bay sits on Keoneoio lava flows—the youngest on Maui—formed during eruptions in the late 1700s, a landscape later frequented by Hawaiian fishers and voyagers.
