Tahiti Iti, Tahiti's smaller sister island that's connected to the main island at the southeast coast, is home to one of the most famous surfing waves in the Pacific, Teahupoo. This powerful reef break most certainly should not be attempted by anyone but the best surfers—a fall means being dragged by the current across the sharp coral right below the surface. That edge of drama makes for a tense but enjoyable afternoon of observation (from the beach). The left break is best between April and October. The Billabong Pro competition is held here August.
