Barracuda Lake
Definition
Barracuda Lake is a brackish lake in a limestone crater on Coron Island, Palawan, Philippines, reached by a climb over jagged karst from the shore. The lake’s remarkable thermocline — layers of water shifting from warm to hot with depth — and its underwater limestone pinnacles make it one of the Philippines’ most distinctive freediving and diving sites.
Named for a barracuda once said to inhabit its waters, the lake lies within the Tagbanwa ancestral domain and is managed under the community’s tourism rules.

Examples and Analogies
Barracuda Lake is a thermal layer cake for divers: warm at the surface, hot in the middle depths, and cool again below — with limestone walls descending like underwater mountains.
Usage Scenarios
Freedivers and scuba divers explore the lake’s walls and thermocline; day-trippers climb the karst stair for swimming; the site pairs with Kayangan Lake and Twin Lagoons on Coron’s lake circuit.
Strategies
The Tagbanwa community manages access fees and site rules within the ancestral domain, coordinating with Coron tour operators on the island circuit.
Security and Safety Measures
The karst climb requires careful footing; divers observe thermocline safety and buddy protocols; the site’s rules protect the lake’s unusual water layers and rock formations.
Historical Context
The lake formed in a limestone collapse on Coron Island, its salt water seeping through karst and heated by geothermal gradient at depth — creating the layered temperature profile divers travel worldwide to experience.
Challenges and Controversies
Managing diver traffic in a small lake, and preserving the thermocline experience from crowding, are the site’s continuing management concerns.
