Garuae Pass, Fakarava

Do you like sharks? Then there's Garaue Pass in French Polynesia, which is known for the "wall of sharks" that patrol the reefs immediately outside the pass. Divers will typically descend quickly, sitting on the ocean's bottom as sharks swim just beyond 70 to 90 feet deep. Before starting the ascent, you'll stay for 10 or 15 minutes to view the sharks.

Because of the high currents, divers must have prior experience diving in currents, despite the depth being between 15 and 22 meters. What you see at this diving site is usually a surprise, and large pelagics like the famed Raira can appear at any time (grey reef shark). In the Ali Baba Canyon, shielded from the tide, schools of fish congregate, making for an interesting and colorful dive! You'll probably need to cling to rocks because fighting the strong currents will exhaust you and deplete your oxygen supply quickly. This spot is normally only suggested for advanced divers due to the unpredictable currents, the possibility of large shark sightings (tiger sharks if you're lucky), and the depth.
