Explore Preah Sihanouk’s Cambodian beaches, tropical islands, coastal forests, seafood and changing port city on the Gulf of Thailand.

Preah Sihanouk is Cambodia’s principal coastal province, stretching along the Gulf of Thailand from the port city of Sihanoukville to a mainland coastline of beaches, mangroves and fishing communities. Offshore, a scatter of forested islands gives the province its strongest travel identity: Koh Rong is known for long beaches and a range of accommodation, while Koh Rong Sanloem has a quieter, more secluded character. Smaller islands and protected coastal waters add opportunities for snorkelling, diving and boat excursions, although conditions and access vary with the weather.

Sihanoukville, also known historically as Kampong Som, is the province’s administrative and transport centre. Its urban landscape has changed rapidly through port expansion, construction and investment, producing a less uniform atmosphere than the island resorts or the older coastal settlements. Beaches such as Otres, Independence and Serendipity offer different experiences, from broad sandy stretches and waterside accommodation to busier urban recreation. Visitors should expect ongoing development in parts of the city and should check current access arrangements before relying on a particular beach or business.
Away from the built-up coast, Ream National Park protects a varied landscape of mangroves, estuaries, low forest, beaches and offshore islands. Boat trips through its waterways can reveal a more natural side of the province, while Kbal Chhay Waterfall, inland from Sihanoukville, is a popular local outing during the wetter months. The rural districts around Prey Nob and other coastal communities provide a different perspective, with rice cultivation, small-scale fishing and seafood trade continuing alongside tourism and port-related activity.
Preah Sihanouk’s modern history is closely connected with Cambodia’s emergence as a maritime trading state in the twentieth century, but the coast also reflects much older patterns of seaborne commerce. The province’s name honours King Norodom Sihanouk, under whose reign the modern port was developed. Today, travellers come for island beaches and warm water, yet the region is more than a resort strip: it combines a strategically important port, a changing Cambodian city, protected coastal ecosystems and communities whose livelihoods remain tied to the sea. Seafood, Khmer cooking and tropical fruit are central to the local food scene, while the islands offer a slower rhythm than the mainland.

Getting to and around Preah Sihanouk

How to get there

Preah Sihanouk is served by Sihanoukville International Airport, located within the province and outside the main urban centre; available international and domestic services change, so confirm routes before travelling. The railway links Sihanoukville with Phnom Penh and other Cambodian destinations on operating days, while road travel from Phnom Penh commonly uses National Road 4. Long-distance buses and private transfers also connect the province with Phnom Penh, Kampot and other parts of Cambodia. Ferries and speedboats to Koh Rong and Koh Rong Sanloem generally depart from the Sihanoukville area, but operators, piers and schedules can change.

Transportation

Sihanoukville is spread along a developing, hilly coastline, so private cars, hired drivers, taxis and tuk-tuks are useful for reaching beaches, the port and inland sites. Local ride-hailing and taxi availability can vary, particularly outside the central urban area. Travel on the islands is more limited: visitors usually arrive by boat and then walk, use local boat transfers or arrange transport through accommodation, depending on the island and beach. Ream National Park and Kbal Chhay Waterfall are easier to reach by private vehicle or organised excursion than by public transport. Roads and building activity can alter journey times.

Best attractions in Preah Sihanouk

Preah Sihanouk’s attractions are divided between its mainland coast, protected landscapes and offshore islands. Koh Rong and Koh Rong Sanloem provide the province’s best-known beach experiences, with sandy bays, forested interiors and opportunities for swimming, snorkelling, diving and boat trips; facilities and atmosphere differ considerably from one beach settlement to another. On the mainland, Sihanoukville’s beaches include busier urban stretches as well as quieter areas around Otres, although development has changed their appearance and access over time. Ream National Park offers a coastal environment of mangroves, estuaries, low forest and islands, best explored through a locally arranged boat or guided excursion. Kbal Chhay Waterfall is a popular inland outing during the wet season, when streams are fuller. Wat Leu, set on a hill above Sihanoukville, combines a temple visit with broad views towards the city and coast. Markets, seafood stalls and port-side activity provide cultural interest, while rural districts reveal fishing, agriculture and everyday provincial life beyond the resort areas.

Best landmarks in Preah Sihanouk

Sihanoukville’s most recognisable modern landmark is its deep-water port, the infrastructure that transformed the former Kampong Som area into Cambodia’s principal maritime gateway. It is primarily a working facility rather than a conventional sightseeing attraction, but its presence explains the city’s strategic importance and rapid growth. Wat Leu occupies a prominent hill above the urban area, with Khmer Buddhist architecture and elevated views across Sihanoukville and the coast. The beaches and headlands around Independence and Otres are geographical landmarks as well as recreational spaces, although their visual character continues to change through construction. Offshore, Koh Rong and Koh Rong Sanloem form the province’s defining natural landmarks, combining forested ridges, reefs and long beaches within the Gulf of Thailand. Ream National Park’s mangrove channels, estuaries and island-fringed coastline represent another important landscape landmark, showing the ecological setting that existed before large-scale coastal development. Kbal Chhay’s rocky stream and waterfall provide a contrasting inland feature, particularly during the rainy season when water flows through the surrounding forest.

Best restaurants in Preah Sihanouk

Dining in Preah Sihanouk reflects both Cambodia’s coastal food traditions and the province’s international visitor economy. Fresh seafood is central, with fish, squid, prawns, crab and shellfish appearing in grilled dishes, soups, stir-fries and Khmer preparations flavoured with lemongrass, lime, garlic, pepper and fermented fish. Sihanoukville’s markets and waterside restaurants offer the broadest choice, while beach settlements on Koh Rong and Koh Rong Sanloem tend to focus on seafood, Cambodian staples, Western comfort food and simple cafés. Amok, lok lak, noodle dishes, rice plates and fresh tropical fruit are widely available, though not all are specifically regional creations. Kampot pepper and other produce from Cambodia’s south-west may feature on menus without implying that they originate in Preah Sihanouk. In the city, Chinese, Southeast Asian and international restaurants reflect the province’s changing commercial connections, while smaller local eateries often provide the most economical meals. Standards and opening arrangements vary on the islands, so visitors with dietary requirements should communicate them clearly.

Best bars in Preah Sihanouk

Evening life varies sharply between Sihanoukville and the islands. The city has bars, hotel lounges, karaoke venues and restaurants serving visitors, workers and long-term residents, but its nightlife landscape has changed repeatedly with redevelopment and changing regulations. On Koh Rong, beach bars and casual restaurants provide the most concentrated evening activity, particularly around the main inhabited settlements, while Koh Rong Sanloem is generally quieter and more oriented towards relaxed drinks, dining and the night sky. Traditional Cambodian beer gardens and local eateries are common parts of the mainland evening scene, alongside establishments aimed at international travellers. Live music and informal beach gatherings may occur, but schedules and venues are not dependable year-round. In smaller coastal communities, nightlife is usually modest and centred on food, conversation and family or local social life rather than clubs. Drink responsibly, take care near the water after dark and arrange transport in advance where roads or boat services are limited.

Best shops in Preah Sihanouk

Shopping in Preah Sihanouk is practical and varied rather than concentrated in a single historic retail quarter. Sihanoukville has supermarkets, convenience shops, markets and independent businesses serving local residents, construction workers and tourists, while beach areas offer clothing, beach equipment, snacks, handicrafts and informal souvenirs. Mainland markets are useful for fruit, seafood, spices and everyday Cambodian ingredients, although hygiene and refrigeration standards differ between stalls. On Koh Rong and Koh Rong Sanloem, small shops and resort boutiques carry essentials, but prices can be higher and choice narrower because goods arrive by boat. Good regional purchases include Cambodian pepper, dried seafood, palm-based products, woven items, locally made crafts and packaged snacks, provided they are bought through legitimate sellers. Art galleries and craft shops are more likely to be found in larger urban areas than in rural coastal settlements. Visitors should avoid buying coral, shells, wildlife products or antiquities, and should carry reusable bags to reduce plastic waste in island communities.

Preah Sihanouk essentials

Currency and Payment
The official currency is the Cambodian riel (KHR), but United States dollars are widely used in Sihanoukville and on the better-established islands, especially for accommodation and tourism services. Prices may be quoted in dollars, with change often returned in riel or a mixture of currencies. Cards and contactless payments are increasingly accepted in hotels, larger restaurants and established businesses, though connectivity and terminals are less dependable in rural areas and on smaller islands. Carry clean, smaller dollar notes and some riel for markets, local transport and informal food stalls.
Safety
Use ordinary precautions with phones, wallets and passports, particularly around busy transport points, nightlife areas and beaches. Road traffic can be unpredictable, and helmets and appropriate insurance are important if hiring a motorbike; visitors should avoid riding after drinking. At the coast, heed flags and local advice, as currents, sudden weather changes and boat traffic can make swimming hazardous. Strong sun, dehydration, mosquitoes and slippery paths around waterfalls are practical concerns. Check accommodation and beach conditions before travelling because rapid development can affect access and the local environment.
Emergency Situations
Cambodia’s national emergency numbers are commonly listed as 117 for police, 118 for fire and 119 for ambulance services. Coverage and response times can be less predictable on islands and in rural districts, so keep your accommodation’s contact details and arrange boat or road assistance through a trusted local operator when necessary. For serious medical problems, treatment options are more limited outside Sihanoukville, and comprehensive travel insurance with medical evacuation cover is advisable. On boats, follow crew instructions, use the supplied life jacket and avoid travelling when conditions are clearly unsafe.
Do's and Don'ts
Dress modestly when visiting temples or local communities, covering shoulders and knees, and remove shoes where requested. Ask before photographing people, fishermen, religious ceremonies or private property. At beaches and on islands, avoid littering, damaging coral, collecting shells or disturbing wildlife. Bargain politely in informal markets rather than treating negotiation as a confrontation, and agree fares before using local transport. Tipping is not compulsory but is appreciated for good service; check bills carefully and keep valuables secure without displaying large amounts of cash.
Local Tips
Plan island stays around the season and sea conditions rather than assuming every boat runs daily. The mainland and islands have different rhythms, so combine beach time with a visit to Ream National Park or a local seafood market if schedules allow. Kbal Chhay Waterfall is generally more rewarding after rain but can be less suitable for swimming during strong flows. Buy water in refillable containers where possible, and bring reef-safe habits to marine excursions. In Sihanoukville, allow time for traffic, construction and changing commercial areas rather than relying on outdated online listings.

History of Preah Sihanouk

Early Maritime Trade on the Cambodian Coast

The coast around present-day Preah Sihanouk formed part of wider maritime networks linking mainland Southeast Asia with the Gulf of Thailand, the Malay Peninsula and beyond. Archaeological evidence from the broader Cambodian coastal zone points to long-standing movement of goods, people and technologies by sea, while rivers and estuaries connected coastal communities with inland settlements. The region was not always a political centre comparable with Angkor, but its sheltered waters, islands and access to maritime routes gave it continuing economic importance. Fishing and coastal trade remained fundamental activities long before modern tourism or port construction.

Kampong Som and the Khmer Coastal Kingdoms

For much of its recorded history, the area was known as Kampong Som and was connected to the shifting political and commercial world of Cambodian kingdoms. Its coastal communities operated within a landscape influenced by Khmer authority, neighbouring states and seaborne traders. The islands and mainland inlets were difficult to control continuously, yet they offered useful anchorages and access to forest and marine resources. Religious, linguistic and cultural influences travelled along the coast, leaving Preah Sihanouk linked to the wider history of Cambodia rather than isolated from it.

French Colonial Rule and Coastal Administration

During the French protectorate, Cambodia’s coast was incorporated into colonial administrative and commercial systems that prioritised mapping, resource extraction and regional transport. The territory did not become a major urban centre during this period, but colonial rule helped formalise administrative boundaries and strengthened links between the coast and Phnom Penh. The development of roads and communications also laid groundwork for later state-led investment. In the twentieth century, the coastal area’s strategic value became more pronounced as Cambodia sought a modern port capable of handling international trade.

The Creation of Modern Sihanoukville

The modern port and city were developed in the 1950s after Cambodia gained independence. The port, opened in the early 1960s, provided the country with an important maritime outlet and reduced reliance on routes through neighbouring states. The settlement increasingly became known as Sihanoukville, in honour of King Norodom Sihanouk, while Kampong Som remained an important historical name. Port construction, roads and public buildings transformed a lightly developed coastal area into a nationally significant city and helped establish the province as Cambodia’s principal gateway to the sea.

War, the Khmer Rouge and Reconstruction

The province was affected by the conflicts that engulfed Cambodia during the 1960s and 1970s. Its port and coastal position made it strategically important during the Vietnam War period, while the Khmer Rouge era brought violence, displacement and the collapse of normal economic life. The port city and surrounding communities suffered major disruption, as did the country’s transport and administrative systems. After the fall of the Khmer Rouge regime and the gradual restoration of national stability, Sihanoukville resumed its role as a port, industrial centre and coastal destination.

Tourism, Investment and Rapid Urban Change

From the late twentieth century, Sihanoukville’s beaches and islands attracted increasing numbers of Cambodian and international visitors. Tourism expanded particularly on Koh Rong and Koh Rong Sanloem, while the mainland saw port-related industry, hotels, roads and large construction projects. Chinese investment and casino development accelerated urban change during the 2010s, bringing employment and infrastructure alongside concerns about planning, environmental pressure and the displacement of established businesses. The province remains in transition, balancing a strategic port economy with marine conservation, local livelihoods and the long-term future of its island and beach tourism.
