Another breathtaking island that’s yet to be destroyed by foreign investment, Koh Ta Kiev is just one hour away from Sihanoukville by boat and close to Ream National Park. It’s delightfully unspoilt and even though it’s the closest Cambodian island to the mainland retains that castaway island feel. At the moment, there are no ATMs on the island so make sure you stock up on cash before you leave the mainland if you want to spend the night here.
