Harley Reef

Harley Reef is a shallow offshore reef site in Guam’s western coastal waters, offering straightforward diving for local and visiting divers. The reef slopes gently from a few meters to around a dozen meters, with healthy hard corals, nursery areas for reef fish, and opportunities to see small to mid-sized tropical species common to Micronesia. Access is typically by boat from near coastal towns, with calm conditions prevailing on most days. The site is suitable for beginner to intermediate divers, provided currents are light and visibility is fair. Expect a relaxed drift or gentle current along the reef crest, with macro life and schooling fish more likely along the edges. Nearby towns in the area include Piti, Asan Municipality, and Hågat Municipality, all within easy reach for pre-dive logistics and exit points.
