We have taken many night buses on this trip. On the one hand, they’re great because we save on paying for accommodation for the night. On the other, they stink because we arrive exhausted in a new city at 5am and end up sleeping for half a day.
But the night bus to Siem Reap was great because it was a sleeper bus. Essentially, bunk beds lined the length of the bus, with double “beds” on one side of the aisle, and singles on the other. This bus even had pads on the platforms and blankets. It was by far the most comfortable night bus we’ve taken.
Most people come to Siem Reap to visit Angkor. The temples that make up the largest religious monument on earth were built over four centuries from 875 to 1230, first as Hindu places of worship, but later converted to Buddhist temples.
Scattered throughout the forest are hundreds of temples in various states of ruin. Many of them are built in the “temple mountain” architectural style. The biggest and best preserved complex is also the most well known, Angkor Wat.
Bayon temple, in the Angkor Thom complex, is unique with its 216 faces.
We really enjoyed wandering through the nearly empty Preah Khan, which, unlike Angkor Wat and Bayon temple is one storey.
In some areas, nature has won, and the jungle is reclaiming its territory. But this makes for some really unique photos. Ta Prohm, where Lara Croft: Tomb Raider was filmed, is the most dramatic example. 
We’ve visited a lot of temples in Asia, and they can start to look similar. However, the temples of Angkor were so impressive, they’re not sights we will soon forget.
Beer of choice: Angkor (a lager like every other beer in Asia)
