Stonehenge - Similan Islands

Stonehenge feels like an ancient gathering of massive granite boulders, tumbled together over eons. We weave through swim-throughs and around these giant rocks, keeping an eye out for leopard sharks often resting on the sandy bottom, along with schools of snapper and fusiliers. It’s a site that rewards careful exploration, perfect for divers who appreciate the drama of geological formations as much as the fish life. Strong currents can pick up here, so it’s best for those comfortable with drift diving.
