Top 15 tips for snorkeling Molokini Crater
A little preparation makes a big difference on a Molokini trip. Here’s what we tell friends before they go.

- Go in the morning. The water is usually calmest and clearest early, before the trade winds pick up.
- Pick your departure point. Mākena and Kīhei are much closer to Molokini than Māʻalaea; the big catamarans from Māʻalaea trade a longer ride for more space and amenities. See how to get to Molokini.
- Match the boat to your group. Families with young kids do best on big catamarans with slides and flotation; adventurous groups love rafts. Compare every tour.
- Plan for seasickness. If you’re prone to it, take medication the night before and again in the morning, eat a light breakfast, and sit near the back of the boat looking at the horizon.
- Use mineral, reef-safe sunscreen. Hawaii bans sunscreens containing oxybenzone and octinoxate. Apply it before you board.
- Wear a rash guard. A long-sleeve swim shirt protects your back from the sun better than any sunscreen.
- Leave the full-face mask at home. Many operators don’t allow them. The boat will provide a standard mask and snorkel.
- Wear prescription lenses? Ask about optical masks; several boats carry them.
- Use the flotation. A noodle or vest lets you relax and float rather than tread water, and nobody will think twice.
- Defog your mask. Use the boat’s defog or a drop of baby shampoo, rinse lightly, and keep the mask on your face rather than on your forehead.
- Look, don’t touch. Never stand on, kick or touch coral, and don’t feed the fish. Molokini is a protected Marine Life Conservation District.
- Give turtles room. Stay at least 10 feet away from sea turtles and never chase or touch them.
- Stay with your group. Keep the boat in sight, snorkel with a buddy, and listen to the crew’s briefing on where to swim.
- Try the back wall only if you’re confident. The outer wall drops into deep water and can have currents. It’s spectacular, but it’s for strong snorkelers on calm days.
- Bring a camera, a towel and a layer. An underwater camera or phone case captures the clear water, and a light jacket helps on the windy ride home.
