Preah Sihanouk province is Cambodia's most famous beach town. Better known as Kampong Som to locals, it is about 230 km southwest of Phnom Penh and boasts pristine white-sand beaches, unspoiled tropical islands, and a dynamic nightlife. With its palm-studded shores and warm, clear waters, it hardly comes as a surprise that Preah Sihanouk attracts crowds of locals, expatriates, and tourists eager for a beachside holiday. Do as locals do and enjoy the stretches of powdery white sand with a chilled coconut and some toothsome grilled seafood. Or, indulge in a beachside massage, take a dip in the sea, and go for dinner in any of the local restaurants that serve fresh crabs, prawns, lobsters, fish, and scallops in a mouth-watering array of styles.

There are dozens of untouched islands off the coast of Preah Sihanouk: Koh Rong and Koh Rong Samlon both feature blissfully uncrowded beaches with palm-shaded shorelines. Being a beach town, there are also many sea-based activities for adventuous visitors, including boating, island-hopping, fishing, diving and snorkeling in crystal clear waters. For the expert enthusiast who wants to explore the mysterious underwater world of coastal Cambodia, the province has PADI Dive Centers and qualified instructors who know just the right spots to take you. In the evenings, the nightlife heats up, and those in search of pulsing bars and nightclubs won't be disappointed. Many entertainment venues, especially those on Weather Station Hill, stay open well into the wee hours.
