5Samaesan Hole, Samaesan Bay, Thailand

This incredible hole penetrates deep into the earth at around 85m deep. With its incredibly strong currents, if you are not well prepared for this dive, then it can take some divers severely off course.

In addition to these strong currents, a surprising site are the unexploded bombs. The Samaesian hole is a former military dumping ground, providing a unique but dangerous experience for any diver.
