Sihanoukville is Cambodia’s best-known beach resort town with some great stretches of sand, tropical islands and the mangrove jungles of Ream National Park. Set around a deepwater port on the Gulf of Thailand, the provincial capital of Sihanoukville is lined with palm fringed beaches, seafood restaurants, and late night bars. Overlooking the capital is the hilltop Buddhist temple of Wat Leu.
