Board a luxury catamaran from Kailua‑Kona for a 4.5‑hour snorkel and dolphin‑watch cruise to the Red Hill marine sanctuary—two hours in the water, island‑style fare, and a high chance of marine mammal sightings. Read on for what to expect and how to plan.
The sun lifts off the Pacific in a slow, liquid motion as the double-decker catamaran eases away from Kailua‑Kona Pier. Salted breeze threads through the teak rails, the boat’s hum becoming a steady heartbeat beneath the chatter of pre-dawn coffee cups. Passengers trickle out onto shaded decks, towels slung over shoulders, reef-safe sunscreen gleaming on forearms. Within twenty minutes the shoreline thins, lava cliffs flatten, and the open ocean opens a confident, blue expanse that seems to dare you into the water.

Check in 30 minutes before departure at the Ilima Court retail store to allow time for parking and the short walk to Kailua Pier.
Sunscreen is provided, but bring extra to reapply after snorkeling; it protects both your skin and the reef.
Waves and the waterslide mean phones and sunglasses can go overboard—use a waterproof case or leave valuables ashore.
Two hours of water time is comfortable but active; wear fins and a flotation device if you tire easily.
The Kona coast was a navigational route for early Hawaiian voyagers; marine areas like Red Hill sit near lava flows that shaped this shoreline over centuries.
The operator provides reef‑safe sunscreen and enforces no‑touch policies to limit coral damage; guests are encouraged to respect wildlife distances and avoid standing on reefs.
Core apparel for getting in and out of the water and for sun protection between swims.
Protects electronics from spray and unexpected splashes during on‑deck activities and the slide.
Blocks wind and adds a layer for cooler mornings or choppy returns to shore.
Staying hydrated on the water reduces fatigue and sun risk during long exposure.
