Cambodia’s Beaches: The Hidden Tropical Paradise

Beyond the magnificent temples of Angkor Wat, Cambodia holds a stunning coastline ready for discovery in the South of the country. Along the Gulf of Thailand, a scattering of idyllic islands and surprisingly wild coastlines reveal a simple, authentic beauty. From the turquoise waters of Koh Rong to the sublime sunsets on Koh Rong Samloem and the tranquil atmosphere of Kep, Cambodia's beaches captivate travellers seeking serenity. Less crowded than the famous coasts of Thailand or Vietnam, they offer a discreet charm, perfect for an off-the-beaten-track beach holiday.

1. Best time to visit Cambodia’s beaches

Cambodia enjoys a tropical climate defined by two main seasons: the dry season and the rainy season.

The ideal dry season: November to April

The dry season runs from November to April. This is undoubtedly the best time to fully experience Cambodia's best beaches. The sky is clear, the sea is calm, and the water boasts a brilliant blue—perfect for swimming, snorkelling, or long, lazy days on the sand. The months of December to March offer the most pleasant conditions, with temperatures comfortably sitting between 25°C and 30°C.

The quieter rainy season: May to October

The rainy season, from May to October, brings frequent showers, especially in the afternoon. While some islands can be harder to reach due to winds and rougher seas, this period has its own appeal: the landscapes are lush and green, prices are lower, and there are fewer crowds.

For a perfect Cambodia beach holiday, aim for November to April, when the sunshine and calm seas invite you to discover the untouched beauty of the Cambodian coast.

3. Practical tips for enjoying Cambodia’s beaches

Before setting off to explore the Cambodian coast, here are a few helpful tips for a successful beach holiday:

• Currency and budget: The local currency is the Cambodian Riel (KHR), but the US Dollar is widely accepted, especially in tourist areas. The beaches and islands remain very affordable compared to those in Thailand.

• Getting around: Ferries from Sihanoukville reach Koh Rong and Koh Rong Samloem in 30 to 45 minutes. Remember to book your round-trip tickets in advance, especially during the high season.

• Preparation: Pack sun cream, mosquito repellent, a hat, and sunglasses—the tropical sun is strong even when hidden behind clouds.

• Connection and electricity: Island areas sometimes have limited internet connection. Take the opportunity to disconnect! Electrical sockets are types A, C, and G, compatible with European adapters.

• Local respect: Cambodians are warm and welcoming. A smile or an "Arkun" (thank you in Khmer) is always appreciated. On quieter beaches, avoid leaving rubbish or stepping on corals—the preservation of these places depends on it.

The beaches of Cambodia are not just places of relaxation but genuine invitations to dream. Between the softness of Koh Rong Samloem, the serenity of Kep, and the wild beauty of Koh Tonsay, every stretch of sand tells a different story. Away from the hustle, time is suspended by the sound of the waves and the scent of salt.
