Barracuda Lake

A landlocked lake on Coron Island reached by a short boat ride and a climb over a rocky ridge. Cool freshwater sits over a hot, mineral-rich salt layer, with a shimmering thermocline around 14m where the salt layer can hit about 38C. Marine life is sparse; it is dived for the strange conditions and rock formations.
