North

Northern Cambodia is best known for the Angkor Temples located a few minutes north of Siem Reap. You can also visit the surrounding Tonlé Sap Lake, Kulen Mountain, Koh Ker (one of the older capitals of the Khmer empire) and more.

At the northern border separating Cambodia and Thailand, one can visit the Preah Vihear Temple aka Prasat Preah Vihear. Though many of the temples found in Cambodia display interesting designs both Hindu and Buddhist, Prasat Preah Vihear is a uniquely Hindu temple. Some of the walls are caved in, building blocks tumbled to the ground, and burn marks evident from previous wars and battles. At the time of this writing, relations between Thailand and Cambodia are peaceful, but it is good to double-check before visiting.

Situated South of Prasat Preah Vihear and the Dangrek Escarpment is the city of Anlong Veng, a good place to grab a local meal. It looks like many other Cambodian cities, but is better known as the cremation site of Pol Pot (actually near Dangrek Escarpment). This was one of the first cities ravaged by Pol Pot's tyranny and one of the initial "Killing Fields".
