About
Barracuda Lake is one of the most unique diving and snorkeling experiences in the world. This volcanic lake sits in a limestone crater with water temperatures that shift dramatically, from 28°C at the surface to 38°C at depth, creating visible thermoclines that blur your vision like a mirage.
Named after a giant barracuda skeleton found in the lake, the underwater scenery is otherworldly. Massive limestone boulders and walls create a cathedral-like environment, and the incredible visibility (15m+) makes it feel like flying through an alien landscape.
Even without diving, the lake is stunning for swimming and snorkeling. The access involves a short but steep climb over rocks from the boat dock.
Local tip
If you dive, the thermocline effect at 14-16 meters is incredible: your vision goes blurry as you pass through the temperature boundary. Even snorkelers can feel the warm patches.
