Island Speed Ferry checks in at its main office at the Sihanoukville Autonomous Port, next to the Giant Ibis bus office. Other ferry companies may board elsewhere, so go where your ticket says, 30 minutes before departure. ### How far is Sihanoukville airport from the city? 20 km south-east of the city centre, next to Ream. Airport taxis cost from about USD 15 by the airport's figures; there is no airport bus. ### Can I go straight from Sihanoukville airport to the Koh Rong ferry? Yes, by taxi or Grab to the Autonomous Port. Leave a good margin before your boat: flights can land late, and check-in closes before departure. With an afternoon landing, a night in town and a morning ferry is the safer plan. ### Is the train or the bus better from Phnom Penh to Sihanoukville? The bus is faster, about 3 to 4 hours for about USD 18. The train takes 6 hours 36 minutes for USD 12, once a day at 07:00, and runs through Takeo and Kampot. ### How do I get from Sihanoukville to Siem Reap? By Giant Ibis night bus at 19:00, arriving the next morning, or by flying from KOS, which lists flights to Siem Reap. ### How do I get from Sihanoukville to Kampot? By the 14:00 train, 2 hours 12 minutes for USD 7, or by van or bus in about 2 hours 30 minutes from about USD 10, sold online for October 2026. ## Where this comes from 1.
