Boulder maze with swim-throughs and rich reef life.
Green Rock is a boulder-field dive site with swim-throughs, caverns, and narrow passages that attract dense reef life. It suits intermediate divers who are comfortable with changing current and overhead sections, and it rewards slow, buoyancy-aware navigation through mixed rock formations, sheltered pockets, and more exposed edges. Good briefings and steady trim make the dive more comfortable.
