It's a 358-stone-step climb up Phnom Banan to reach Prasat Banan, but the incredible views across surrounding countryside from the top are worth it. Udayadityavarman II, son of Suryavarman I, built Prasat Banan in the 11th century; some locals claim the five-tower layout here was the inspiration for Angkor Wat, although this seems optimistic. There are impressive carved lintels above the doorways to each of the towers and bas-reliefs on the upper parts of the central tower.
From the temple, a narrow stone staircase leads south down the hill to three caves, which can be visited with a local guide.
Prasat Banan is 23km south of Battambang.
