Off the west coast of Kalimantan (Borneo) lies a group of Indonesian islands called the Tembelanarchipelago. Administratively a part of the Riau Islands Province, they offer visitors myriad opportunities to swim and snorkel in an idyllic setting. The Tembelan islands are small, partly inhabited dots of land lying just north of the Equator. Nature here is still pristine and wild. Large rocks sitting on the edge of the water, coral, white-sand beaches lined with coconut trees, green hills and fishing villages: these are the many faces you will be lucky enough to discover on these exotic and charming islands where sea turtles are often spotted.
