Relax on Pristine Beaches
The Southern Islands are home to some of Southeast Asia’s most beautiful beaches. From the soft, powder-white sands of Koh Rong to the secluded coves of Koh Rong Sanloem, these coastlines are perfect for sunbathing, strolling, or simply soaking in the tropical serenity. With fewer crowds than neighbouring countries, you’ll often find stretches of beach entirely to yourself. Whether you prefer barefoot luxury or rustic charm, the beaches here invite true relaxation in an unspoilt natural setting.
Snorkelling and Diving
The warm waters surrounding Cambodia’s Southern Islands offer excellent snorkelling and diving. Explore coral reefs teeming with colourful fish, sea turtles, and occasional reef sharks. Koh Tang and Koh Prins are popular spots for diving excursions, while the shallow reefs off Koh Rong Sanloem make snorkelling easy for beginners. Several eco-friendly dive centres provide professional guidance. It’s a rewarding way to discover the marine life of the Gulf of Thailand while supporting sustainable underwater tourism.
Island-Hopping by Private Boat
One of the best ways to experience the Southern Islands is by private boat. Charter a day trip or a sunset cruise to explore lesser-known islets, snorkelling spots, or hidden beaches inaccessible by land. Island-hopping allows you to visit local fishing villages, spot dolphins in open waters, or enjoy a gourmet picnic on a deserted beach. It’s a luxurious yet simple pleasure that lets you enjoy the islands at your own pace, far from crowds.
Kayaking through Mangroves
Paddle through the mangrove channels of Koh Kong or Koh Ta Kiev for a peaceful and immersive experience in the island ecosystems. These calm waterways are perfect for kayaking and offer a close-up look at Cambodia’s coastal biodiversity. Spot birdlife, crabs, and small fish as you glide through the shaded trails of trees and roots. Many eco-resorts offer guided mangrove kayaking tours that combine nature discovery with responsible travel, adding a deeper layer to your island stay.
Stay in a Luxury Eco-Resort
The Southern Islands are dotted with eco-conscious luxury resorts that blend sustainability with comfort. Whether on Koh Russey or Song Saa Private Island, you’ll find stylish villas built from natural materials, farm-to-table dining, and spa therapies overlooking the sea. These resorts support local communities and conservation efforts, offering guests a sense of purpose alongside indulgence. A stay here lets you enjoy Cambodia’s natural beauty while helping to preserve it for future travellers.
Watch Bioluminescent Plankton
On moonless nights around Koh Rong and Koh Rong Sanloem, the sea comes alive with glowing plankton. A night swim in these sparkling waters is a magical and unforgettable experience. As you move, tiny plankton emit bursts of light, creating a galaxy of luminescence around you. Some guided night boat trips offer the best spots for safe viewing. It’s a rare natural phenomenon, best seen in calm, dark conditions—and one of Cambodia’s most enchanting coastal moments.
Enjoy a Sunset Beach Barbecue
Many resorts and private boat charters can arrange beach barbecues at sunset—one of the most enjoyable dining experiences on the islands. As the sun dips into the Gulf of Thailand, savour freshly grilled seafood, tropical fruits, and Khmer-inspired dishes under lantern-lit skies. With your feet in the sand and a drink in hand, it’s a romantic or family-friendly treat. This relaxed, al fresco setting embodies the laid-back charm of Cambodia’s island lifestyle.
Trek through Jungle Trails
Beyond the beaches, the Southern Islands offer short jungle treks that reveal hidden waterfalls, coastal cliffs, and diverse wildlife. On Koh Rong, you can hike from one side of the island to the other, passing through thick forest and small villages. Koh Ta Kiev and Koh Sdach also have easy trails through cashew trees and bamboo groves. Guided treks offer insight into local flora and fauna, making it a rewarding way to connect with the islands’ wild interiors.
