In November we entered Cambodia at the Poipet border, we left Thailand to embark on our journey through Cambodia. During our trip we were able to experience many places:
The Angkor temples
The capital city, Phnom Penh
Sihanoukville (but we mainly stayed in Otres Village)
We actually altered our trip, we had a few other destinations planned prior to arriving but changed the route to allow for some rest time.
