Koh Tonsay or Rabbit Island is located about 4.5 kilometres southwest of Kep. The sea here is shallow, making Koh Tonsay excellent for swimming. Here, you’ll find a variety of corals, sea animals and plants which attract researchers and ecologists. A few locals live on the island, but you will need to bring with you whatever you need for the day. Boats can be arranged through guesthouses. For those seeking a relaxing day trip, this is highly recommended.
