DAY 2: STUNG TRENG – THE RUINS OF ANGKOR – SIEM REAP (B/L)
After breakfast, check-out your room and drive to Siem Reap. Notice the road condition of this journey may vary according to the season and can be bumpy in the wet season. 
Stop en route to visit the ‘sacred sanctuary’ Preah Vihear temple, while listening to your guide sharing a little bit more about the history of this incredibly inspiring temple. Recognized as a UNESCO World Heritage site since 2008, Preah Vihear Temple is located on the heart of a plateau that dominates the plain of Cambodia. 
The next visit is the stunning Koh Ker which was built from the 8th to 10th centuries for a short function as the capital of the Khmer Empire. The Koh Ker temple is nestled away deep in the jungle and was inaccessible due to the mines until 2007. Nowadays, thanks to the projects of the Cambodian Mine Action Centre, some of the sanctuaries have been slowly coming to life again. If you don’t mind, climb up the wood staircases to the top of the temple to admire the stunning view over the surrounding plains and jungles. Get your camera ready to capture some great views. 
After exploring the temple, head to Siem Reap, a gateway to the ancient temple ruins of Angkor.
 
Notes:
Road conditions may vary according to the season and can be bumpy in the wet season The Koh Ker temple has steep wood staircases to climb up to the peak.
