Angel's Window
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.
Angel's Window is the reminder that Lembeh has coral too. A pinnacle in the strait's clearer northern reaches, it is pierced by a tunnel whose frame of fans and soft corals gives the site its name and its classic photograph. Sea fans on the deeper faces host Bargibanti pygmy seahorses, ribbon eels flare from holes in the rubble, and clouds of anthias and cardinalfish soften the edges. Guides often run it as a two-act dive, working the window and fans first, then grazing the base for nudibranchs and shrimp. For strait veterans sated on sand, it resets the eyes; for new arrivals it flatly contradicts the idea that Lembeh is only muck.
The moment you come for: The fan-framed swim-through; pygmy seahorses; a reef interlude amid the muck itinerary.
Topography: Coral pinnacle riddled with a swim-through window, sea fans on the deeper faces, rubble at its base.
Current: More flow than the sand sites, as the pinnacle stands in the strait's northern tidal stream.
Know before you splash
Hazards: Current around the pinnacle and depth at the window; keep the passage brief and orderly when groups queue.
Nitrox: Worth it here: profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).

"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.
