Guests aboard the 55-foot Hula Kai catamaran visit snorkeling and scuba locations along a 10-mile secluded stretch on the South Kona coastline. Highlights include underwater lava arches, historic lava flows and sea caves. It's not unusual to spot dolphins, whales, manta rays and, of course, fish such as tangs and triggers. All snorkel gear is included. Scuba gear is also available with experienced guides to assist with instruction.

After snorkeling, guests gather for a barbecue served alongside a scenic location. Post-barbecue, everyone can settle back with a drink to take in the Kona sunset.
