Nick Ray is the author of the Phnom Penh and Siem Reap chapters of Lonely Planet's Cambodia guidebook, which was published in September 2025.

For the longest time, travelers to Cambodia only had eyes for the temples of Angkor, but in recent years, the beaches and islands dotting the south coast have become one of the country's major attractions.

Sunseekers are spoiled for choice in Southeast Asia, with legendary beaches tracing the shores of Indonesia, Malaysia, Thailand, Vietnam and the Philippines, and Cambodia can compete with the best of them when it comes to powdery sands, swaying palms and turquoise waters.

If you're in the mood for a bit of Cambodian island-hopping, the idyllic isles off the coast near Sihanoukville entertain die-hard party people as well as folks seeking sun-smooched solitude. And getting to Cambodia's islands is easy, with regular ferries and longtail boats setting out from the mainland coast.

All you need to do to find beach perfection in Cambodia is pick your island, choose your beach and sprawl on the sand surrounded by warm, clear waters. There's a reason that many visitors to Cambodia's beach towns check in and never check out!

Whether you crave a crowd or a calm escape, here's our guide to the best beaches in Cambodia.

The best time to visit Cambodia's beaches

It pays to consider the climate when planning a beach trip to Cambodia. From November to March, the beaches and temples bask under mostly dry skies, and temperatures are warm but not overpowering. This is also the best time to dive on the reefs around Koh Rong, but rates peak at Cambodia's beach resorts in this high season.

Rainfall is moderate in April and early May, though temperatures can climb to uncomfortable levels, often reaching 35°C (95°F). The soggy monsoon months from June to September are not ideal for a beach day; it doesn't rain all day every day, however, and this coincides with the summer vacation season in Europe, North America and Oceania, so there are still plenty of visitors to the south coast.

1. Lazy Beach, Koh Rong Sanloem

Best for families

On the southwest coast of Koh Rong Sanloem, this hideaway is home to one of the most stunning beaches you’ll find anywhere. There is only one place to stay here, Lazy Beach – the agreeably rustic resort that gave the beach its name.

The basic bungalows have balconies and hammocks to take in the splendor of the sands, and the combined restaurant and lounge area is well stocked with books and board games, making this beach a good fit for families.

2. Koh Tonsay, Kep

Best for a taste of the old Cambodia

On the mainland near Kampot, Kep was Cambodia's original beach resort, attracting the glamorous and beautiful in its heyday before the civil war. While a little of the polish has come off in the decades since, it's still an appealing hangout and a popular resort for locals, who are lured here by family beach fun and the city's famous peppered crab.

For a touch more peace, head to Koh Tonsay (Rabbit Island), about 20 minutes by boat from Kep. On weekdays, a tranquil mood pervades the island's sandy, palm-backed beaches, and there's decent snorkeling if you have your own gear. Locals gather for pocket-friendly seafood feasts on the weekends.

A flashy new resort is under construction at the southwestern tip of the island, so focus your attention on the main beach, where a handful of bungalows offer chilled-out accommodation, inexpensive meals, hammocks to sway in and boat trips to tiny Koh Puos and Koh Svay, where you may spot dolphins.

Planning tip: Boats to Koh Tonsay depart from the Rabbit Island Pier near Kep's main beach.

3. Koh Ta Kiev, Sihanoukville

Best for an island getaway from Sihanoukville

If your dream beach escape involves switching off and tuning out, then the little island of Koh Ta Kiev, off the coast near Ream National Park, will tick all the boxes. Although developers are circling, for the moment the southern tip of the island retains its castaway mood.

On arrival, you'll find a clutch of delightfully bohemian and eco-friendly budget digs and the impressive Long Beach to sprawl on. This is where the backpacking vibe of Otres Beach lives on under the watchful gaze of high-rise Sihanoukville.

Planning tip: Resorts on Koh Ta Kiev arrange transfers by longtail boat from Otres Beach or Ream Beach near Sihanoukville.

4. Long Set Beach, Koh Rong

Best for a low-key island experience

Also known as 4km Beach, thanks to its ample proportions, this stunning stretch of sand graces the south coast of Koh Rong island. It takes its name from one of the first resorts to set up shop here. A handful of hostels and boutique resorts now line up behind the greenery-backed sands, but it is still peaceful and relatively undeveloped compared to neighboring Koh Tuch.

To the west, Long Set is connected to busy Koh Tuch via a short forest walk, passing the rather lovely Tree House Bungalows.

Detour: At the extreme east end of Long Set Beach, behind Koh Rong Hill Beach Resort, a short path leads to nearby Nature Beach, another pretty spray of sand that feels more exclusive.

5. Koh Thmei, Sihanoukville

Best for unplugging

Koh Ta Kiev isn't the only idyll basking off the coast near Sihanoukville. Closer to the Vietnamese island of Phu Quoc than Sihanoukville, Koh Thmei has serene, sandy beaches backed by tropical greenery. Perhaps its greatest attraction: no roads, cars or phone signal – perfect if you want to truly escape from it all.

There's just a single resort – an off-grid work of art, full of contraptions that minimize its ecological footprint. Everyone gets their own hammock swinging on the front deck, and board games and listening to the sounds of nature are the main activities in the evenings. With no other settlement or business on Koh Thmei, there's every chance you’ll have the island to yourself.

Planning tip: The Koh Thmei Resort handles transfers from the pier by Ouchomna Market, about 35km from Sihanoukville, accessible via the minivans that run from Phnom Penh to Sihanoukville.

6. Lagoon Beach, Koh Kong Island

Best for pristine water

Off the coast north of Sihanoukville, Cambodia’s largest island rises out of seas so clearly that you can almost make out individual grains of sand in the shallow waters. The island has seven beaches arrayed along the west coast, backed by coconut palms and lush vegetation, just as you’d expect in a tropical paradise.

Several of the best beaches are at the mouths of little streams – we strongly recommend the sixth beach, known as Lagoon Beach, where a narrow channel leads to a hidden lagoon.

Planning tip: To access Koh Kong Island, you'll need to book a boat tour from Koh Rong city or Tatai on the mainland; direct buses and minivans run to Koh Kong city from Phnom Penh, Kampot and Sihanoukville.

7. Long Beach, Koh Rong

Best for serenity

Hugging the western shore of the idyllic island of Koh Rong, Long Beach – also known as Sok San Beach – is the island's finest escape. The almost empty stretch of beyond beautiful sands runs for 7km. The squeaky sand is so soft that you might be forgiven for thinking there had been an explosion in a baby powder factory.

Confusingly, the beach is sometimes known as 7km Beach, due to its length, and Royal Sands Beach, in honor of the resorts that lie at the northern and southern ends. In case the beachfront looks familiar, the strip was used as a key filming location for the US television series Survivor.

Planning tip: Motos (motorcycle taxis) can zip you around the island to other beaches, or you can charter a longtail boat for beach-to-beach transfers.

8. Koh Sdach Islands, Koh Kong

Best for secluded snorkeling and diving

The Koh Sdach archipelago is a cluster of 12 small islands, many of which have good snorkeling and scuba diving. The main island – Koh Sdach (King's Island) – lacks beaches, but it's a great place to experience island life without the crowds.

From here, you can hire a boat to explore nearby islands with blissfully empty beaches, including Koh Totang, the sand spits of the Koh Ampil islets, and the long white beaches on either side of Koh Smach. This is definitely one for adventurous beachcombers.

Planning tip: Boats to the Koh Sdach Islands leave from the southwestern tip of Botum Sakor National Park. You can make arrangements with the Koh Sdach Resort or agencies in Koh Kong city.

9. Lonely Beach, Koh Rong

Best for sustainable living

Lonely Beach is a bolt-hole hidden away on a private beach at Koh Rong's northern tip. There is a strong commitment to sustainability at this low-key eco-resort; cute bungalows, and open-air dorms are cooled by sea breezes and all water is dispensed via coconut-shell scoop.

High season brings excursions to other islands, snorkeling trips and nightly banquets on the beach. Don't be surprised if you never want to leave; some travelers who end up here extend their stay by months.

Planning tip: The resort offers transfers via a daily boat service, leaving from Sihanoukville's Royal Pier.

10. Saracen Bay, Koh Rong Sanloem

Best for going barefoot

Blessed with endless sands and steamy jungles, Koh Rong Sanloem is tropical perfection. The island has three main settlements, each with its own distinct personality. There's no doubt that crescent-shaped Saracen Bay is the most beautiful, with a graceful curve of white sand hemming the island’s eastern shoreline.

If you are weighing Koh Rong versus Koh Rong Sanloem, the latter is calmer and has a more barefoot vibe, with less development behind the sand. There are few roads on the island, so walking or chartering a longtail boat is the default way to get around.

Planning tip: Resorts to suit every budget are strung along 2.5km of sand. This bay is well connected to Sihanoukville by high-powered speedboats, and ferries shuttle across to nearby Koh Rong.
