Following defeat at Angkor by the Thais, the Khmer capital moved to Oudong, and kings ruled from there for more than 100 years until the power center shifted to nearby Phnom Penh in 1866. The area was a monastic center, and the 13th-century temples, like most others, pale in comparison to those of the Angkor complex. Still, the hills of Oudong offer breathtaking views. It's 1 hour west of Phnom Penh and is best reached by rented vehicle.
Phnom Chisor & Tonle Bati
If you've been or are going to Angkor Wat, these temples will pale in comparison, but the ride through the countryside and among rural villages makes for a good day. Tonle Bati (33km/21 miles south of Phnom Penh) is a small collection of Angkor-style temples. Entrance costs $3. Nearby Phnom Chisor is a group of 10th-century ruins atop a picturesque hill. Phnom Penh travel agents can make all the arrangements.
