Kanaio Sea Caves to La Perouse: South Maui Boat & Snorkel Adventure
From lava arches to Molokini’s crystalline walls, this South Maui boat run pairs dramatic coastal geology with memorable snorkel stops. It’s a half‑day at sea that favors early starts, reef‑safe habits, and a readiness for changing marine conditions.
The Experience
Before You Go
Arrive Early for Check‑In
Plan to be at the picnic tables by 6:30 a.m. for a 7:00 departure — the crew boards on a strict schedule.
Bring Reef‑Safe Sunscreen
Apply reef‑safe, waterproof sunscreen before boarding and reapply after snorkeling to protect coral and your skin.
Wear Secure Footwear
Light slip‑on water shoes with grip help when stepping on wet docks or lava at La Perouse Bay.
Plan for Motion and Currents
If you get seasick, take medication the night before and again pre‑departure; currents around Molokini can pull you along while snorkeling.
Local Knowledge
Hidden Gems
- •Compression caves along the Kanaio coastline — best seen in low swell from the boat.
- •Quiet lava fingers at La Perouse Bay where tidepools hold small fish and invertebrates.
Wildlife
- •Hawaiian green sea turtle (honu)
- •Spinner dolphins and occasional manta sightings
Conservation Note
The area includes protected reef habitat — follow guide instructions, avoid touching coral or turtles, and use reef‑safe products to reduce impact.
La Pérouse Bay is named for the 18th‑century French explorer who charted these shores; the bay’s black lava is among the island’s more recent historic flows.
