Lighthouse Reef
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily, so treat everything here as planning ranges.
Lighthouse is Malapascua's sunset ritual. As the light dies, mandarinfish emerge from the staghorn rubble in courting pairs, spiraling upward for a second-long spawning embrace that photographers wait out with red-filtered torches and held breath. The dive around that appointment is a slow shallow mooch: seahorses clinging to sponges, pipefish on the sand, juvenile everything sheltering in the coral scree, and squid gathering as darkness settles. Depth rarely passes 8 m, so the whole affair runs long and warm. It pairs naturally with a thresher-heavy itinerary, small drama after the morning's big one.
The moment you come for: Mandarinfish spawning at dusk, seahorses and pipefish, long mellow twilight profiles
Topography: Rubble, staghorn thickets, and sand in the lighthouse's shadow
Entry: A short ride to the island's northwest corner, timed so the dive starts in the last half hour of daylight.
Know before you splash
Hazards: Shallow boat traffic at dusk; long exposure to stinging hydroids for the careless.
Conservation: Mandarinfish abandon rubble patches that get blasted with white light and crowding; follow the low-light etiquette.

"Charted here" species were listed by our editors from the sources on this page. Counts are GBIF occurrence records: observations logged within about 5 km of the charted position since 1990, matched only against the species in our catalogue. They show what has been seen there, not a promise of what you will see.
