Gun Beach is located at the northern end of Tumon Bay and is named after the World War II gun placements that use to adorn the area. Today it is a nicely isolated beach that offers one a place to relax, away from the hussle and bussle of more trafficed areas. It is also a good place to snorkel and dive. The waters off the reef are quite clear. However, as with all beach areas exercise caution because lifegaurds do not patrol this area.
