Depart from the Kailua Pier and sail down the scenic Kona Coast to Red Hill, a marine sanctuary and prime snorkeling spot that's only accessible by water. Get comfortable on the double-decker catamaran featuring a shaded cabin with cushioned seating and tables, an upper sundeck, and three restrooms with freshwater showers. Enjoy a light breakfast when you board and a grilled buffet lunch midday, plus beer, wine, and blended drinks from the premium cash bar.
Get basic snorkeling instruction, if you need it, and then explore the reefs with provided snorkeling gear. You can also splash into the water via a high-dive platform or deluxe waterslide, try out a stand-up paddleboard or “Seaview board,” or simply bob up and down in a floating relaxation station. Above the surface, keep an eye out for spinner dolphins that often pass nearby.
