Traveling from Siem Reap to Koh Kong is a significant journey, covering approximately 390-400 kilometers (around 240-250 miles). A private car journey usually takes around 8 to 10 hours, depending on traffic, road conditions, and any comfort stops you choose to make.
Our primary route will take you from Siem Reap first on National Road 6 (NH6), heading southeast. This will lead you towards Phnom Penh. Before reaching Phnom Penh city center, you will connect to National Road 5 (NH5), and then to National Road 4 (NH4), which is the main highway connecting Phnom Penh to Sihanoukville. Along NH4, specifically in Kampong Speu or Koh Kong province, you will turn onto National Road 48 (NH48). This road leads directly into Koh Kong City. The roads are generally in good condition for most of this long journey.
