Lighthouse is a boat-access Puerto Princesa Bay reef that starts as sand and coral patches before building into caverns, sea-fan-covered outcrops, and narrow rocky cuts along the bay headlands. The dive feels like a deeper scenic reef rather than a wall, with a mix of open slope, darker structure, and small hideouts that reward both wide-angle passes and careful macro searching. Divers usually treat it as an experienced-level site because moving water is common and visibility changes with the tide. On clearer runs it offers schooling fish, nudibranchs, frogfish, rays, and occasional bigger pelagics over the reef line, while low tide can make the bay water noticeably more silty and the dive less forgiving.
