Koh Rawi: Koh Rawi is next to Koh Adang and is roughly the same size. This mountainous island has beaches, which disappear into the lush forests of the interior. While Koh Rawi does not offer the same accommodations as the other islands, it is still a wonderful place to explore and enjoy the scenery. The viewpoint at Koh Rong Kuai offers panoramic views of the island as well as beautiful sunrises and sunsets.
