Sao Tome: Boca do Inferno

Boca do Inferno (aka Hell’s Mouth) is a natural blowhole formation off the western coast of São Tomé and a major attraction. Basaltic lava has formed a platform over the ocean and a narrow channel where the pounding waves push water that explodes up in the air in spectacular fashion. The rougher the surf – the higher the water blasts. You can actually get down onto the platform and be behind the channel and in front of the ocean – probably not the safest place to be for the risk of being swept away, but exhilarating nonetheless.
