Thach Dong Cave Pagoda
On the road to the Cambodian border, 4 km (2.5 miles) northwest of Ha Tien, this cave pagoda is in an echoey cavern in a limestone karst, with various chambers holding funerary tablets. The cave is home to a colony of bats (so keep your mouth closed when you look up), and the views from some of the openings across to Cambodia are pretty. At the base of the mountain is a small monument shaped like a clenched fist that commemorates the murder of 130 local civilians by the Khmer Rouge in 1978.
