During the times when swimming is safe—mainly in summer—just about every beach on Molokai offers good snorkeling along the lava outcroppings in the island's clean and pristine waters. Certain spots inside the South Shore Reef are also worth checking out.
Kepuhi Beach. In winter, the sea here is deadly. But in summer, this ½-mi-long west-end beach offers plenty of rocky nooks that swirl with sea life. The presence of outdoor showers is a bonus. Take Kaluakoi Road all the way to the west end. Park at Kaluakoi Resort (it's closed) and walk to the beach.
Waialua Beach Park. A thin curve of sand rims a sheltered little bay loaded with coral heads and aquatic life. The water here is shallow—sometimes so shallow that you bump into the underwater landscape—and it's crystal clear. To find this spot, head to the east end on Route 450, and pull off near mile marker 20. When the sea is calm, you'll find several other good snorkeling spots along this stretch of road.
Rent snorkel sets from either Molokai Outdoors or Molokai Fish and Dive in Kaunakakai. Rental fees are nominal—$6 to $10 a day. All the charter boats carry snorkel gear and include dive stops.
Fun Hog Sportfishing. Mike Holmes, captain of the 27-foot powerboat Ahi, knows the island waters intimately, likes to have fun, and is willing to arrange any type of excursion—for example, one dedicated entirely to snorkeling. His 2½-hour snorkel trips leave early in the morning and explore rarely seen fish and turtle posts outside the reef west of the wharf. Bring your own food and drinks; the trips cost $65 per person. Kaunakakai Wharf, Kaunakakai, 96748. 808/567-6789.
Molokai Fish and Dive. Climb aboard their 27-foot cabin cruiser or 31-foot twin hull Power Cat for a snorkel trip to Molokai's pristine barrier reef. Trips cost $69 per person and include equipment, water, and soft drinks. 61 Ala Malama St., Kaunakakai, 96748. 808/553-5926.
