Preah Sihanouk (Sihanoukville) (ព្រះសីហនុ)

Capital: Sihanoukville  · 230 km from Phnom Penh · 4h by road · 45min by flight

The coast — and gateway to the islands. Sihanoukville town itself has changed dramatically (heavy Chinese casino development since 2018), but skip past it to Otres, Ream National Park, or the boats to Koh Rong and Koh Rong Sanloem for the white sand and clear water Cambodia is famous for.
