Begin with pickup at select Waikiki hotels at your chosen departure time (morning or afternoon). Climb into the tour vehicle for the brief ride to the Ko Olina Marina and Resort, where you'll check in on the dock and munch on some provided snack and sip tea, water, and coffee.
Meet your captain as you step aboard the 53-foot (16-meter) catamaran and set out for your day's first stop. As you cruise, you can relax on deck and watch the Hawaiian scenery pass by or explore the boat. The catamaran is fully equipped with a fully stocked bar, a teak interior, and freshwater showers. There is plenty of room for 40 passengers to spread out and get comfortable.
Once you reach your first destination, get fitted for a mask and snorkel and jump in to the water, a known habitat for the local spinner dolphins. Float around the coral reef in search of native marine life. Upgrade with a SNUBA excursion, a technique that is a combination of snorkeling and scuba diving.
After two reef visits, dig into a Hawaiian-style lunch of soy-veggie burgers, chicken teriyaki, and pulled pork sandwiches. Guests over age 21 can sip two complimentary cocktails along with lunch.
As the boat heads back to shore, enjoy the scenery, soak up some sun, or head below deck for a freshwater shower. Once you return to land, get dropped off back at your Waikiki hotel.
