A Guide to Khmer Temples in Thailand & Laos  

Thaicouses.com comments:
One of my personal favorites—craft your own unique vacation in Thailand by seeking out the spectral ruins of 13th century Khmer temples scattered across Thailand's arid northeast. You won't run into other tourists and will discover fantastic sites, usually having them all to yourself (except a few curious Thais wondering how you lost your way). In my opinion, checking off some of these obscure sites makes a fantastic pretext for exploring Thailand its beautiful people at your own pace. Best of all, you'll have the help of Freeman's guidebook, with maps, directions, and history. But don't worry, you'll still get lost and have plenty of adventures—I only found this book half-way through my own quest for the ruins, and, in comparing with my notes from sites I had already visited, found enough minor glitches in Freeman's work to keep you asking the locals where to go. Highest recommendation.
