If you'd prefer to take a snorkel cruise to Kealakekua Bay in a small boat, go in Captain Zodiac's 16-passenger, 24-foot inflatable rubber life raft. The boat takes you on a wild ride 14 miles down the Kona Coast to Kealakekua, where you'll spend about an hour snorkeling in the bay and then enjoy snacks and beverages at the picnic snorkel site. Trips are twice daily, from 8:15am to 12:15pm and from 12:45 to 5pm. Warning: Pregnant women and those with bad backs should avoid this often-bumpy ride.
