Great sight, must visit in Battambang, they fry out from the cave between 5 until 6 in the evening. I paid 10 $ to get there, you can book the tour with the hotel is more reliable. on the mountain top you can see the Buddha Temples, and the great beautiful panoramic green view. Battambang is the second largest city in Cambodia, but not so many place to visit, I stayed in Battambang for two nights. anyway I really love Battambang because there is not so many tourists here.
