Photo: Farid Askerov whereisfarid, CC0A crescent of volcanic rock rises about 3 miles off Maui's south coast, and its protected inner cove is one of the clearest places to snorkel in Hawaii. You cannot swim or kayak there. A morning boat gets you in the water before the trade winds build, and the reef rules are strict for good reason.
What you see is the rim of a partly submerged volcanic crater, with a curve that shelters an inner cove from the open channel. Tour operators and guides describe reef fish in numbers inside the cove, and deeper drop-offs on the outer back wall that drift-snorkel trips target. The islet itself is a seabird sanctuary, so you look at it from the water. Fishing, feeding, collecting and landing are prohibited.
Subzone A of the conservation district is the sheltered cove on the concave side of the crescent. Most boats moor here, and the water is typically calm and clear on a good morning.
Small boats and some rafts run drift snorkels along the outside of the crescent, where the bottom drops away and current is stronger. Better for confident swimmers on a guided trip.
Expect yellow tang, Moorish idol, parrotfish, reef triggerfish and butterflyfish. Spinner dolphins sometimes show up on the crossing, and humpback whales can be seen from December to April. None of this is guaranteed.
A bright lemon-yellow surgeonfish that grazes algae in loose schools. It is one of the easiest Hawaiian reef fish to spot, especially along the Kona coast.
Zebrasoma flavescens
A striking black, white and yellow fish with a long trailing fin, often seen in pairs or small groups over Pacific reefs.
Zanclus cornutus
Colorful grazers with fused, beak-like teeth. You can hear them crunch on coral rock, and much of the white sand on tropical beaches passes through them.
Scaridae
Hawaii's state fish, with a famously long Hawaiian name and bold, painted-on stripes. It patrols shallow, surgy reef and grunts when it is caught.
Rhinecanthus rectangulus
Small, disc-shaped fish in yellow, white and black patterns, usually seen in pairs. Many feed on coral polyps, so they are a good sign of a healthy reef.
Chaetodontidae
Slender dolphins famous for leaping and spinning. They rest in calm Hawaiian bays by day after feeding offshore at night, which is why the law protects their daytime rest.
Guardian rule: Federal law bans swimming with or approaching spinner dolphins within 50 yards in Hawaii.
Stenella longirostris

We may earn a commission when you book through these links, at no extra cost to you. It never changes which tours we pick. How we choose tours.
Tours run year-round when the channel allows. Operators and guides point to roughly May to September as the calmest, most consistent stretch, while winter trips often add humpback whales on the crossing. Boats cancel or switch sites when wind or swell is too high.
Book the earliest departure. Guides recommend 6 to 8 a.m. starts because trade winds build through the day and roughen the crossing and the water. Most morning boats are heading back by late morning.
Tides matter little here; wind and swell decide the day.
Skip afternoon trips in windy weather, and days of strong trade wind or big swell, when visibility and comfort both drop. Ask the operator about its cancellation policy before you book.

Molokini is boat only. It sits several miles offshore in an open channel, so private visits mean a charter or your own vessel and a day-use mooring. For most visitors a licensed tour is the way to go. Wear the flotation the crew offers, since current can run on the outer wall.
Swim level: Comfortable swimmer
Molokini is reachable only by boat. Most big catamarans leave Maalaea Harbor, and smaller rafts also run from the Kihei Boat Ramp. You cannot swim, paddle or land. Check in 30 minutes or more before departure.
Parking is at the harbor or ramp you depart from. Maalaea Harbor has lots near the docks, and your operator will tell you where to leave the car. At the Kihei Boat Ramp, parking is limited, so arrive early and follow the sign on your booking.
You board at the dock or ramp and enter the water from the boat, usually by ladder or slide, over a mooring in the inner cove or along the outer wall.
About 20 to 45 by raft or catamaran from Maalaea; shorter from Kihei by raft minutes each way. Boats leave from Maalaea Harbor, Kihei Boat Ramp.
No entry fee, but you need a boat tour. Fishing, feeding, collecting and landing on the islet are prohibited.
Official fees and hoursChecked 2026-10-22. Fees change, so confirm before you go.
Molokini is the visible rim of a volcanic crater, protected as a state conservation district for decades. Boats tie to day-use moorings in the inner cove and let you snorkel the reef along the crescent. The cove is usually clearer and calmer than the open channel, but the weather decides everything, so be ready for the crew to switch you to another site if the wind is up.
Choose between a large catamaran with a meal and a slide, or a smaller raft that runs faster and drift snorkels the outer wall. Many itineraries add a second stop at Turtle Town or a reef near Makena, but not all do, so read the listing. Prices change often, so check the operator page. Tours here are booked directly with operators.
Go in the morning, and favor late spring to early fall for the steadiest water. In winter, humpback whales add a bonus on the crossing but swell and wind cancel more trips.
Molokini Shoal is a state Marine Life Conservation District with two zones: the inner cove (Subzone A) and the outer waters out to 100 yards (Subzone B). Maui County also requires mineral sunscreen.
Taking or injuring any marine life is prohibited, as is possessing devices that could take it. Do not remove or alter sand, coral or other geological features. Official rule
Feeding fish or putting attractants in the water is banned, with a narrow exception for trolling in Subzone B only. Official rule
Molokini is a seabird sanctuary and landing is prohibited. Anchoring is banned where the state has set day-use moorings, and commercial mooring needs a permit. Official rule
Maui County allows only mineral sunscreen with zinc oxide or titanium dioxide. A rash guard is the simplest fix. Official rule
Keep at least 50 yards from spinner dolphins and 100 yards from humpback whales, including from the water. Keep 10 ft from turtles. Official rule

No. Molokini is a crescent islet in the channel about 3 miles off Maui's south coast and can be reached only by boat. Landing on the islet is prohibited because it is a seabird sanctuary.
Most leave from Maalaea Harbor on Maui's south-central coast, and some smaller trips use the Kihei Boat Ramp. Your booking names the dock or slip, so check it before the day.
Guides give a range of about 20 to 45 minutes depending on the boat and departure point. Rafts are faster than big catamarans. A full trip is usually 4 to 5 hours including a second stop.
Early morning. Trade winds build through the day, and morning boats see calmer water and a smoother crossing. Book a 6 to 8 a.m. departure if you can.
It is a Marine Life Conservation District. No taking or injuring marine life, no feeding fish, no removing coral or sand, no landing on the islet, and no commercial mooring without a permit. Maui County also requires mineral sunscreen.
The inner cove is typically calm, and boats supply flotation and a briefing, so it suits beginners on a guided trip. Wind and current can change that, so ask the crew about the plan for the day.
