Tonle Bati is a small lake about 30 km south of Phnom Penh. It is a popular weekend destination for the local population. It is also a popular fishing spot for both tourists and people who live locally. Close to the lake, there is the Ta Prohm of Bati, one of several shelters built in Cambodia and Thailand during the reign of Jayavarman VII to house the Jayabuddhamahanatha statues. It is located off the highway to Takéo Province.

The word Jayabuddhamahanatha means "Victory-Buddha-Great Saviour" and may be have been referred to the defeat of the Chams by the king Jayavarman VII. A similar sculpture was found at the Vihar Prampil Lvengo on the Avenue of Victory at Angkor Thom.

20 minutes south of the lake there is another temple called Phnom Chisor. It is situated on a mountain top which requires a visitor to climb 461 steps.
