Best Water Activities in Maui

Snorkeling (Free to $120+)

The most accessible water activity on Maui. Shore snorkeling is free at multiple sites near Kihei. The reef off the lawn at Maui Sands Seaside gives guests immediate access without a car. Boat snorkel tours to Molokini Crater run $80 to $120 per person and represent the premium end of the snorkeling experience. Both the free shore option and the paid boat option are worth doing at least once.

Stand-Up Paddleboarding (SUP) ($25-$50/hour rental)

South Maui's protected water and consistent morning calm make it ideal for SUP. Rental shops along South Kihei Road open by 7 a.m. A sunrise paddle in glassy water before the trade winds build is one of Maui's understated pleasures. Lessons are available for beginners. Advanced paddlers can explore the coastline south toward Makena. In whale season, paddling along the shore in the early morning occasionally yields close encounters -- if a whale surfaces near you, stop paddling and let it pass.

Kayaking ($30-$60/half day rental)

Sit-on-top kayaks are stable, easy to use without prior experience, and give access to snorkel sites that are unreachable on foot. The kayak route south from Kihei toward Turtle Town and Makena Landing is popular and well-marked. Guided kayak-snorkel tours are also available for those who prefer a structured experience with a guide who knows where the turtles feed.

Surfing ($60-$90 lesson)

The south and west shores of Maui are gentle enough for beginners, especially at Kihei's north-end break near the boat ramp. Most visitors take a group lesson and find they can stand by the end of the hour. The North Shore (Ho'okipa) and parts of the west coast are for experienced surfers only -- do not paddle out at a wave break you do not understand. Group lessons in Kihei are the right starting point; instructors provide soft-top boards that are far more forgiving than standard shortboards.

Whale Watch Tours ($40-$80) -- December to April Only

The Pacific Whale Foundation and other operators run responsible educational whale watches from Maalaea Harbor. Two hours on the water during peak humpback season (January and February) gives near-certain sightings. The scale of a humpback -- up to 50 feet, up to 45 tons -- does not become real until you are fifty feet away watching one breach. Shore watching from the unit 711 lanai is excellent, but one boat tour during the season is worth adding to the itinerary. See our complete whale season guide.

Sunset Sailing ($90-$140)

Several operators run two-hour sunset sails from Maalaea Harbor and Lahaina. The classic Maui sunset from the water -- Lanai silhouetted against the orange sky with the trade wind filling the sail -- is hard to beat as a one-time experience. Most tours include drinks and light snacks. Trilogy Excursions and Ocean Riders are well-reviewed. Book at least a day in advance in high season.

Scuba Diving ($100-$180)

Maui's dive sites include Molokini Crater's back wall (advanced), Mala Wharf (night dives), Cathedrals off Lana'i (advanced), and a range of South Maui reefs suitable for beginners on their first open-water dives. Certified divers will find enough variety here for a full week of two-tank days. Maui Dive Shop, Lahaina Divers, and Shaka Divers are established operators with solid reputations.

Kitesurfing and Windsurfing

Kanaha Beach in Kahului, on the north shore, is one of the best kitesurfing and windsurfing sites in the world. The consistent trade winds that frustrate south-shore snorkelers are exactly what kitesurfers and windsurfers come to Maui specifically to find. Lessons and rentals are available at Kanaha for experienced practitioners; beginners should expect a multi-day commitment to learn either sport from scratch.
