Koh Rang is a group of small uninhabited islands just south of Koh Chang. Koh Rang Yai is the largest of the islands, boasting tropical rainforests and the longest beach in the area, the Had San Chao or San Chao Beach. Several smaller islands including Koh Tien, Koh Yak and Koh Kra are known for excellent diving and snorkeling, where divers enjoy scenic beauty up to 25 metres deep.

Sailors on a Koh Rang yacht charter should pay a visit to Ao Cho Bay and San Chao Beach, which are probably Ko Rang's best beaches offering crystal clear water.
