Barracuda Lake
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 — treat everything here as planning ranges.
Nothing else in the Philippines dives like Barracuda Lake. Enclosed by Coron Island's karst blades, the lake stacks fresh water over salt, and at about 14 m divers push through a shimmering thermocline into water near 38 °C, hot-bath hot, before it cools again below. The walls are sculpted stone, the silt floor swallows fins whole, and shrimp swarm divers' hands at the margins. A solitary barracuda, the namesake, patrols somewhere in the haze and finds you as often as you find it. Fish life is sparse; sensation is the entire point, and it is worth the gear haul over the rocks.
The moment you come for: A 38 °C thermocline you can feel like a wall, cathedral rock formations, the lone resident barracuda
Topography: Limestone walls, silt cones, and sculpted rock in a brackish crater-like lake
Entry: Boats moor at Coron Island's cliffs; divers carry gear up and over a short limestone stair to the lake.
Know before you splash
Hazards: Heat stress in the hot layer, bottomless flour-fine silt, and deceptive depth in clear, dark water.
Permits & rules: Community-managed entry fee collected at the island.
Conservation: Inside the Coron Island ancestral domain of the Tagbanwa; entry fees support the community and rules deserve strict respect.
