Tarzan Cave is a shore-access Guam cave site with turtles and wreckage.
Tarzan Cave is a shore-access cave site on Guam's south side with a long swim from the Navy Base and plenty of easy visual structure underwater. Old crane, pipes, and other debris sit on the bottom, while hawksbill and green turtles are common and crinoids make the site popular with photographers. It is best treated as a calm-water snorkel or shallow dive with restricted access, not an offshore boat run.

Snorkeling
Snorkeling is a natural fit here, especially for turtle watching and easy viewing in clear water.
