Sihanoukville + Koh Rong

Cambodia's beach coast — gateway to Koh Rong + Koh Rong Samloem islands

Sihanoukville is Cambodia's coastal city — heavily reshaped by Chinese casino investment (many hotels + casinos). The main draw is the ferry to Koh Rong + Koh Rong Samloem islands (paradise beaches, backpacker + luxury tiers). Otres Beach is Cambodia's remaining backpacker beach.
