Palace Wall is a shore wall dive with shallow reef flats.
Palace Wall is a shore wall dive with shallow reef flats.
Palace Wall is a shore-access Guam reef wall with shallow flats, a deep outer wall, and enough structure to support both easy sightseeing and more serious profiles. It works best on calm summer days when the long shore approach stays manageable and the water is clear enough to read the reef. Turtles, rays, barracuda, and other reef fish make the wall lively without turning it into a current-first dive.
