A summer holiday in Cambodia can mean sun-soaked islands, quiet shoreline stretches, an expansive inland lake and riverside wildlife viewing. This article highlights five destinations that are commonly recommended for warm-weather travel in Cambodia, summarises what each offers and provides practical advice for planning a visit.
What a summer holiday in Cambodia looks like
Summer travel in Cambodia often centers on coastal and riverside places where water-based activities and relaxed rhythms dominate the itinerary. From small islands off the southwest coast to the floating communities around a vast inland lake and the Mekong’s river towns, the options combine natural scenery, traditional fishing communities and outdoor recreation.
Typical summer highlights include swimming, snorkeling, short hikes, boat trips and sampling seafood and Khmer dishes in modest local eateries. Many of these destinations are outside the main urban tourist routes, so visitors should expect a quieter pace and more basic infrastructure than in the country’s principal cities.
Key highlights of the five top summer spots
Koh Rong Samloem is a low-rise island west of Sihanoukville that travellers often recommend for calm beaches and clear water. Two of the island’s better-known shoreline stretches are Sunset Beach and Lazy Beach. Accommodation tends to be small-scale — bungalows, guesthouses and boutique properties — with coconut palms lining sections of the coast.
Otres Beach, near Sihanoukville, is split into two sectors commonly called Otres 1 and Otres 2. Both are less developed than the nearby central beach areas and have fishing communities, sand bars and simple beach bars and restaurants serving fresh seafood and Cambodian dishes such as amok and lok lak.
Tonle Sap Lake, south of Siem Reap, is Southeast Asia’s largest freshwater lake and supports a seasonally changing ecosystem. Reports indicate the lake hosts a wide variety of freshwater fish — often cited as over 300 species — and more than 100 species of water birds. Floating villages, stilted houses and large fish traps are features of the communities that depend on the lake.
Phnom Kampong Trach, about 35 kilometres northeast of Kep, is a karst cave complex at the foot of a mountain that contains caverns, religious sites and a freshwater swimming cave. Visitors typically climb a path to viewpoints, explore limestone passages and may choose to cool off in the natural swimming area.
Kampi, a riverside locale roughly 15 kilometres north of Kratie, is known for river safaris to see Mekong Irrawaddy dolphins. Estimates suggest fewer than 100 of these dolphins remain in the Kratie stretch of the river. The area also offers riverside picnic spots such as the Kampi Rapids, a Mekong turtle conservation project and an architecturally distinctive 100 Pillars Pagoda.
Practical tips for timing, travel and what to pack
Seasonality affects travel plans in Cambodia. Rain patterns and water levels change through the year, influencing access to islands and the appearance of inland waterways. For more detail on the wet season and related travel considerations, see the guide to Cambodia weather in September, which explains seasonal risks and practical adjustments visitors often make.
Basic packing suggestions for these destinations include reef-safe sunscreen, a lightweight rain jacket for unexpected showers, sturdy sandals or water shoes for rocky shorelines, and a swimsuit. If you plan to visit caves or trek short jungle paths, bring comfortable walking shoes and a headlamp or torch; for island stays, prepare for limited electricity hours in some guesthouses.
- Transport: ferries and local boats serve islands; domestic buses and private transfers connect coastal towns; small boats are the normal way to visit floating villages and dolphin-viewing sites.
- Money and services: expect fewer ATMs and limited card acceptance in smaller towns and islands; bring cash in local currency.
- Health and safety: typical precautions include drinking bottled water, using mosquito repellent and following guidance from local operators on swimming and boat safety.
Cultural context and community interactions
The places listed are closely tied to local livelihoods. Fishing, small-scale tourism and seasonal agriculture shape daily life around beaches, lakes and rivers. Floating villages on Tonle Sap reveal an adaptation to changing water levels, and riverside communities near Kratie maintain traditions linked to the Mekong.
If you plan to visit villages, polite behaviour and modest dress are appreciated. Visitors report that brief conversations with fishermen, market sellers and family-run guesthouses are typical ways to learn about local customs. When visiting religious sites such as pagodas or shrines in and around cave entrances, follow local protocols: remove shoes, cover shoulders and be respectful of worshippers.

Who will enjoy each destination
Koh Rong Samloem suits travellers seeking quiet beach time with options for snorkeling and short hikes. Otres Beach appeals to people who prefer sparsely developed shorelines, casual seaside dining and evening beach bars without the scale of major resort areas.
Tonle Sap is valuable for travellers curious about freshwater ecosystems and village life — those interested in birdwatching, boating and cultural observation will find it rewarding. Phnom Kampong Trach is a match for visitors who like short climbs, exploring karst landscapes and cooling off in natural pools. Kampi is primarily of interest to wildlife observers and those who want to support or learn about local conservation efforts focused on river species.
- Best for families: Otres Beach offers gentle sandbanks and calm dining options.
- Best for nature enthusiasts: Tonle Sap and Kampi for birds and river mammals.
- Best for relaxed beach stays: Koh Rong Samloem’s smaller resorts and beaches.

Frequently Asked Questions
When is the best time to visit these spots?
Timing depends on your priorities. The dry season generally offers more predictable boat services and lower rainfall, while the wet season changes river and lake levels and can affect access. Consult seasonal guides for specific months and regional differences.
Are these destinations family-friendly?
Many families visit Otres Beach and parts of Koh Rong Samloem because of gentle sand areas and straightforward lodging. For places like Tonle Sap and Kampi, families should consider boat safety and the duration of trips; children often enjoy short river excursions and wildlife watching when organised with experienced operators.
Do I need permits or special arrangements to visit the floating villages or dolphin sites?
Permits are not normally required for tourist visits to floating villages, but boat operators manage access and fees vary. Dolphin-viewing tours are run by local boat operators and conservation groups; hiring a local guide or joining an organised trip is the usual way to visit safely and responsibly.
What wildlife might I see at Tonle Sap and Kampi?
Visitors typically see a range of freshwater fish, water birds and, in the Mekong near Kratie, the Irrawaddy dolphins. Conservation reports note diverse bird populations and numerous fish species at Tonle Sap; dolphin numbers in the Kratie stretch are limited, so sightings are not guaranteed.
How should I choose between a beach island and an inland lake trip?
Choose an island or beach stay if you prioritise swimming, snorkeling and long stretches of sand. Select an inland lake or river town if you want cultural interaction with lakeside communities, birdwatching or river wildlife experiences. Many travellers combine both types of destinations on a longer Cambodia itinerary.
