Without a doubt, Bora Bora's greatest attraction is its consistent warm and sunny climate which remains fairly stable all year round. As a result (and as you may have guessed) the most common outdoor activities on the island all revolve around the beaches and the ocean.
The most popular activities for visitors are swimming and snorkeling in the warm waters of the lagoon. The island is surrounded by a barrier reef which is home to over 500 species of marine life, so there is a lot to discover! Scuba diving trips are also easily arranged, or, if you'd rather reinforce your position at the top of the food chain, you can go on a deep sea fishing excursion. Adventure activities are also popular including jet-ski tours, parasailing and kite surfing.
Up on land there are plenty of options as well. There are several hikes through the jungle, none lasting longer than an afternoon.
