Climbing up the steps of the Angkor Wat, Cambodia

As the country is low-lying, the highest point to be on is the temples. It is a laborious climb up the 80-90 degree steps up the temple ruins with no hand-railings to hold and steps barely wide enough to put your foot on. The hot, blazing sun makes it even difficult as you huff and puff your way up. Reaching the top you are however rewarded with a breathtaking view.
