Favorite thing: Near the parking lot on the Thai side, some students had a project to run an information booth. I guess not many tall farangs make it there. They wanted to take a picture with me. BTW, there are also public restrooms near this parking lot. It is ~0.5 km walk to the Cambodian border from here.
There are several children and adults that will show you around Preah Vihear. Their first language is Khmer but they will know some Thai and English. Laithong and Lawee were selling postcards and accompanied us all the way up, showing us the easier places to walk. The young fellow (I did not catch his name) was a photographer who joined us at the Level 1 temple. Even though we were taking our own pictures, he came to the top with us also. Laithong was the only one who didn't leave when we started back down. They were all polite and helpful, and made the tour very enjoyable.
Fondest memory: Talking and eating jackfruit with the children under the tree at the Level 3 temple.
