Angkor is amazing but be prepared for crowds at the must see temples. We really enjoyed our day with Dara as our guide. He is Ponheary's brother (she is a popular guide people have recommended before). We went to Beg Mealea, Kbal Spean and Banteay Srei. It was a great day and I highly recommend these temples. Of course he told us lots about the temples but we also learned a lot from him about current issues in Cambodia and the difficult history of the past 30 years. He is very interesting. He can be reached through Ponheary's email - email@example.com. Please also check out the great work the Ponheary Ly Foundation is doing. www.theplf.org
We also really enjoyed a 2 hour horseback ride near Siem Reap at the Happy Ranch. The horses are really nice and the ride is out to a little temple, through some rice paddies and by some little villages. It was very nice.
