“Freshwater and saltwater layers create distinct density and temperature Unique diving site with an almost surreal underwater experience Clear waters with some coral and fish Suitable for intermediate to advanced divers Surrounded by limestone cliffs and beautiful natural scenery”
Barracuda Lake is a unique geological feature located on Coron Island. It is notable for its layered water structure: the upper layer (down to 14-18 meters) is freshwater and cool, while the lower layer is saltwater and significantly warmer. This creates a distinct thermocline (temperature change) and halocline (salinity change) phenomenon.
Divers experience a surreal dive unlike anywhere else. As they descend into the saltwater layer, the temperature can rapidly rise, reaching up to 38°C (100°F) at deeper levels, giving the sensation of entering a "hot tub." Divers can explore sharp, cathedral-like underwater rock formations and deep ledges often referred to as a "moonscape."
The lake gets its unusual name from the local legend that a large, resident barracuda inhabits the deeper, warmer parts of the lake. The surrounding area features towering limestone cliffs and stunning natural scenery, making the initial short, steep climb over jagged limestone steps from the boat docking area well worth the effort.
Access to Barracuda Lake requires a boat from Coron town and is usually part of a Coron Island diving tour. Due to the deep, complex rock formations and the rapid thermal changes, visitors are required to have diving equipment, and those with experience will enjoy this unique, memorable dive site most.
