Richelieu Rock (★4.6)
Richelieu Rock is one of the most popular dive sites in Surin Islands National Park. It is a limestone reef that rises almost vertically from a depth of 35 meters, and appears only at low tide, about 1 meter above the surface.
One of the most uniquely beautiful creatures in the sea, the leafy sea dragon lives up to its name. Covered in leaf-like skin filaments, this cousin to the seahorse mimics its environment in a way like no other. The leafy sea dragon is a master at camouflage, blending perfectly amongst the floating kelp beds in which it lives. The ornate leaf-like protrusions hanging from the head, body, and tail do not propel, only camouflage and match the exact color and shape of the kelp and seagrass in which they live, making them practically indistinguishable from their habitat.
