Angkor Wat
Hey Steve, I see you are in Siem Reap now. Here's the travel fish guide I used when I went there in 2008. The wat guide section is still relevant and useful. I URGE URGE URGE URGE you to visit the two outlying temples detailed in page 18 of this document: Banteay Srei and Beng Mealea. I know they are far from Siem Reap but they are sooooooooooooo worth it. Trust me on this dude. Banteay Srei is the most beautiful temple in the entire place and Beng Mealea is just freaking cool. You HAVE to go to them! My trip would have been incomplete without visiting these two places.
