Trach ChaaZ has a new, amazing post here describing a trekking from Koh Kong to Kampong Speu. Must read. Link Trekking from Areng Valley to Roleak Korng Cheung (Aural District)!
The feeling was quite refreshing and full of pride after such a long hike. I was worried about mines along the way but it was fine because there was always trail that people had walked before. Overall, the trip was very challenging, not just physically but also mentally. I had a lot of good reflection about life in general and some personal issues. The food was simple but great and we built a good spirit, which was important. Would not mind doing such a trek again.
