Moorea is known for its worthwhile land and water-based outdoor activities. The island has some of the world's best snorkeling thanks to crystal waters that showcase colorful corals, sea turtles, manta rays, moray eels, dolphins, sharks and more than 500 species of tropical fish. The secluded beach of Opunohu Bay, which offers a serene snorkeling experience, is an especially worthwhile visit. Additionally, Lagoonarium features a closed-off section of a lagoon near Motu Ahi, accessible by a quick boat ride, and gives visitors the chance to swim with hundreds of marine animals as well as nurse baby sharks.
Divers can go deeper into Moorea's underwater world for the chance to see shark dens and deep coral rose gardens. One of the island's top dive sites is Tiki Point, featuring crystal waters and depths of 75 feet (22.8 meters). The spot is plentiful with black tip sharks, grey reef sharks, lemon sharks and sometimes dolphins. There is also the Garden of Roses, which stretches down 120 feet (36.5 meters) to a world-renowned underwater rose garden where sharks love to play. Because this dive can be challenging, an Experienced Diver Certification is recommended, and mandatory with many outfitters. Other notable dive sites include Aito, Shark's Dining Room and the Opunohu Canyons.
Along with underwater adventure, Moorea offers opportunities for land-based exploration, especially through its large trail system. The island features hikes for all levels, offering diverse scenery options as well. The Vaiare to Pao Pao trek is slightly challenging yet scenic, while climbing the 2,951-foot (900-meter) Mt Rotui will provide a more difficult and rewarding experience, making climbers feel like they're in the clouds at the summit.
The trek to Afareaitu Waterfalls is also worth the adventure. Drive down the unmarked dirt road located between the Ah Sing Market and protestant church in Afareaitu until you can't go anymore before getting out and hiking uphill through the jungle and volcanic rock for about 30 minutes to the secluded falls.
Kayaking is another great way to experience the beauty of Moorea's landscape in a relaxing yet active manner. Rentals are available to take out on one of the crystal lagoons.
