Guide to Cambodia's Best Beaches & Islands

2024 Ultimate Guide To Cambodia’s Best Beaches and Islands

Cambodia’s best beaches and islands are all found on the coast of the Gulf of Thailand. Its coastline is spread across four provinces located in the South, Southwest and Northeast, namely Sihanoukville, Koh Kong, Kep, and Kampot.


Cambodia boasts about 60 islands with Cambodia’s most well-known and popular islands being Koh Rong Island and Koh Rong Samloem Island. However, many others are also worth a visit such as Koh Thmei Island, Koh Totang Island and Koh Sampoch.


Depending on what type of island experience you prefer – unwinding on a hammock on an isolated shore, exploring the jungle-clad interior, taking a dip underwater among pristine coral reefs or the nightly magic of bioluminescent plankton, Cambodia has an island for you.

The islands of Cambodia differ in size, shape, and character and as such offer different attractions and experiences for all travellers. Some are popular tourist destinations, while others are secluded and tranquil. Some islands are easily accessible by boat, while other islands require more adventurous travel.

Best Time to Visit Coastal Cambodia’s Islands

The peak tourist season is from November to February when most of Cambodia’s tourists are searching for a relaxing beach vacation.


It’s not advised to visit Cambodia’s beaches from June to September because of heavy rains and humid air. Additionally, the heavy rains leave the sea choppy, affecting transport to and from the islands and the water quality and visibility.


Starting in Kep in the south and moving up the coast to Koh Kong in the northwest; here’s our ultimate guide to Cambodia’s beaches and islands.

Kep Beach – Cambodia’s Best Beach for Families

Starting on the mainland, the small beachside town of Kep is home to a small crescent-shaped white sandy beach. Boasting calm and temperature-perfect water, Kep Beach is Cambodia’s best beach for families, and fantastic for both swimming and sunbathing.


Kep is easily reached from Phnom Penh by bus or minivan. Depending on the traffic and which bus company you use, It takes approximately four hours to reach Kep. You can also reach Kep from the riverside town of Kampot in about 30 minutes by tuk-tuk or scooter. If you want to check out all the transport options use the box below to explore prices and travel times.

Kep Beach is brimming with hammocks and dining platforms with street food stalls and seafood vendors. Making it popular with both tourists and locals alike. This makes for a great place to spend the day, whilst you kick back and relax with great food, a few drinks and a beautiful beach to unwind on. Another attraction that Kep is famous for is its crab market, which happens to be just down the road from the beach. Crabs can be ordered by the kilo, fetched straight out of the water and cooked to your liking. It doesn’t get much fresher than that!

However, it is a popular spot and many visitors come here to snorkel, swim and sunbathe. You can get to Long Beach in two ways. Either a 45-minute walk in the jungle or by taking a boat from the pier. Thankfully, peace remains easy to find, thanks to the island’s 28 beaches.
