The Crevice
A large triangular fold in the cliff just south of the Blue Hole on Guam's outer reef; the site starts at nearly 21 m and has sea fans, whip corals, boulders sheltering turtles, and chance encounters with dolphins, barracuda, tuna and sharks. Local shops recommend an advanced certification and at least 60 dives; best April to December. Boat dive only.
