After visiting Koh Kong Island, facing its southeast corner is your next logical destination, and also perhaps Koh Kong’s most beautiful, in Botum Sakor National Park. With over 180,000 hectares (almost 700 square miles) of natural park to explore, you will encounter a plethora of exotic wildlife, you may not get anywhere else. From elephants, tortoises, tiger and bears, Botum Sakor is also known for hosting quite a selection of rare birds. Accommodations are quite difficult to reach and underdeveloped, so camping is the preferable sleeping method.
Also, without many routes in and around the park, the best way to see it is by boat. However, as you may find yourself mostly alone on this adventure (aside from your guide, of course), the sheer sense of serenity provided here is a once in a lifetime experience.
