With more than 2 million visitors descending on UNESCO World Heritage–listed Angkor Archaeological Park each year, the small, nearby city of Siem Reap has become Cambodia's epicenter for tourism. Once a sleepy, rural town, Siem Reap now bursts with life (although you wouldn't necessarily know it during the day). There are a few sights in Siem Reap itself—notably Cambodian Landmine Museum and School and Angkor National Museum—but the magnificent Angkor temples are the obvious draw, and that's where most visitors spend their days. From watching the sunrise over Angkor Wat to wandering through the ancient Khmer palaces of Angkor Thom and dozens of other atmospheric ruins, you could easily spend three days exploring the vast archaeological site. If you ""temple out"" quickly, or just need to escape the heat for a few hours, book a massage at any number of Siem Reap's relaxing day spas. Or, sign up for a cooking class and learn to make a few Cambodian dishes. In the evenings, head to the vibrant Angkor Night Market for souvenir shopping and a tasting tour of Khmer street food. You might also catch a cultural performance of traditional music or dance. Night owls will find a few more entertainment options on the aptly renamed Pub Street. After the temples, the most popular day trips head south to Tonlé Sap, where lakeboat cruises set sail for the Prek Toal Bird Sanctuary, and glide past the floating villages of Kompong Phluk and Chong Khneas.
