Koh Sdach, an island in the Gulf of Thailand with white sand beaches and clear blue water, is one of Cambodia’s best-kept secrets. It’s also known as the King’s Island, owing to its status as one of the monarch’s properties until the 1970s. Today, it remains one of the country’s least explored islands, despite being just four kilometers off the coast of southern Koh Kong province.

Where Is Koh Sdach Island? 

Koh Sdach, or King’s Island, is a little island off of Kep in southern Cambodia. It’s only a few kilometers long and about 800m across at its widest point. It’s not very big at all. In fact it’s even smaller than Phu Quoc—but what it lacks in size it makes up for with beauty and atmosphere. On weekends young Cambodians from nearby cities flock to the island to spend their day relaxing on loungers, snorkeling around coral reefs and partying on boats anchored off shore at night. If you do manage to get a day trip booked there (not easy), be sure to bring a picnic lunch!

In addition to its natural beauty, tourists can also visit some historical sites from bygone eras including one of King Norodom’s royal temples which was constructed here in 1860. Some visitors enjoy a BBQ lunch on Pelan Beach before heading back to the mainland for dinner. Others opt to stay overnight at an eco-lodge or with a local family.

What Can You Do When You're On The Island?

There are a variety of things to do on Koh Sdach. Explore one of several caves hidden away within its cliffs. To hike to them you'll need to make your way over slippery rocks and around various obstacles — but it's worth it! One cave is home to what looks like a little shrine carved right into stone. It was here that I found myself meditating alone as I sat facing out at the open ocean. For those who prefer staying dry while exploring, take advantage of any boat tours that call into port at Sihanoukville on their way from other islands or mainland sites. You can snorkel or scuba dive with tropical fish and even spot crocodiles and sharks depending on where you head off for your adventure.
