While Thailand often steals the spotlight for its islands, Cambodia’s own collection of over 60 stunning islands in the Gulf of Thailand remains one of Southeast Asia’s best-kept secrets. These islands offer crystal-clear waters, soft white sands, lush jungles, and tranquil vibes—all at a fraction of the cost of more commercialized destinations. Whether you’re seeking luxury, adventure, or complete solitude, Cambodia’s islands promise an unforgettable escape in 2026.

Why Visit the Islands of Cambodia?

Cambodian islands are perfect for travelers who crave serenity, natural beauty, and authentic local experiences. They’re less crowded than their Thai counterparts and ideal for eco-conscious travelers looking to enjoy sustainable tourism. The friendly locals, fresh seafood, and affordable accommodations make these islands a hidden gem in Southeast Asia.

Top Islands to Visit in Cambodia

Koh Rong – The Heart of Cambodia’s Island Life

Koh Rong is Cambodia’s most popular island, famous for its long stretches of white sand and clear turquoise water. Long Beach is perfect for relaxing days under the sun, while Koh Touch Beach offers nightlife, beach bars, and a lively atmosphere.

Adventure lovers can enjoy diving, snorkeling, kayaking, or renting bicycles to explore the island. Dining options range from Khmer favorites at Chai Family Restaurant to Western dishes at Enocafe, Da Matti, or Treehouse Bungalow.

Koh Rong Samloem – The Tranquil Twin Island

Located just a short ferry ride from Koh Rong, Koh Rong Samloem is known for its peaceful environment and dazzling beaches. Saracen Bay is lined with cozy bungalows and eco-resorts, ideal for couples or families seeking relaxation.

Snorkeling here is world-class, with bioluminescent plankton lighting up the waters at night. The northern side of the island hides small waterfalls and mangroves, while the southern end features an old lighthouse with panoramic views.

Koh Ta Kiev – Cambodia’s Untouched Gem

Koh Ta Kiev offers a raw, off-the-grid experience. With limited electricity and WiFi, it’s a place to disconnect from modern life. Three untouched yellow-sand beaches remain free from major development, and accommodation is basic but charming.

Nature lovers will enjoy birdwatching, jungle trekking, and spotting rare orchids. You can also rent kayaks or boats for sunset trips to Elephant Rock for a daring cliff jump.

Koh Thmei – Nature Lover’s Paradise

Part of Ream National Park, Koh Thmei is home to dense mangroves, rich wildlife, and stunning golden beaches. Only around 200 people live on the island, ensuring a peaceful escape.

Expect to see Brahminy kites, fishing cats, and other rare wildlife while hiking or cycling along marked trails. Like Koh Ta Kiev, amenities are minimal—perfect for travelers who want a pure, eco-friendly adventure.

Private Island Resorts: Koh Russey, Koh Krabey & Koh Ouen

For those seeking exclusivity and luxury, Cambodia offers private island resorts that redefine indulgence:

• Koh Russey (Bamboo Island): Home to the elegant Alila Villas Koh Russey, featuring beachfront villas, forest suites, and fine dining.

• Koh Krabey: The Six Senses Krabey Island Resort offers 40 villas, a world-class spa, an open-air cinema, and wellness programs.

• Koh Ouen: Home to Song Saa Private Island, Cambodia’s first luxury eco-resort with overwater villas, yoga retreats, and marine conservation programs.

These islands can only be accessed by guests staying at the resorts, ensuring complete privacy and exclusivity.

Best Time to Visit Cambodian Islands

The best time to visit is between November and April, during the dry season. During this period, the weather is warm, sunny, and ideal for water activities. Avoid the monsoon months (May–October) when travel by boat can be difficult.

How to Get to the Islands in Cambodia

Most Cambodian islands are accessible via Sihanoukville, the main coastal city. Regular ferries and speedboats connect the mainland to Koh Rong and Koh Rong Samloem. For more remote islands like Koh Ta Kiev or Koh Thmei, private boats and local tour operators offer transfers.

Activities to Enjoy on Cambodian Islands
