About this site
The Ridge lies among the Ko Ha Yai group off Krabi in the Andaman Sea, southern Thailand, an area of granite islets and submerged pinnacles reached by boat from the Krabi coast. These offshore formations sit in open water between the mainland and the more distant islands of the region.
