Gun Beach

Gun Beach is a secluded cove at the far end of Tumon Bay. It is considered to be one of the best shore snorkeling in Guam. It includes shallow areas protected by a coral quarry and reefs open onto the ocean, and visitors can explore a range of environments and varied marine life.

Here you will find the best seabed, the diversity of coral is striking, and the underwater life is impressive in density. Shoals of striped monocle bream rest above the coral beds, while surgeonfish and butterflyfish with spectacular colors come and go along the reef.
