Location: Amphoe Photharm
This hill is located in Tambon Tao Pun, Amphoe Photharam, 17 kilometres north of Ratchaburi along the Khao Ngu-Boek Phrai route (Route No. 3089). The roadside hill has 2 interesting caves; Tham Phra Non housing more than 100 Buddha images and Tham Khangkhao or Bat Cave, which is home to some three million bats. As the sun sets over the horizon, they all disperse on their search for food and the mountain looks like a volcano disgorging thick black smoke.
