About this site
Amphitheater lies along Guam's coastal reef in the Mariana Archipelago, on a stretch of the island's fringing reef and limestone shelf typically reached by boat from local dive operators. The site is rated a beginner dive, making it accessible to divers of most experience levels. Guam's coastline here combines shallow reef structure with the steeper drop-offs common to the island's volcanic shelf.
