About L Arch
L Arch is a boat-access L-shaped topography dive off Irabu Island with a long overhead arch, tunnel-like sections, and cave holes that make it a skill-first site. Current can be strong, so the dive rewards controlled buoyancy, calm pacing, and a comfortable attitude around overhead terrain. Expect schooling fish and smaller life around the walls and holes, with the structure itself doing most of the work.
