The Tonle Bati Site is a small lake about 30 km south of Phnom Penh, the capital of Cambodia. There are a scenic lake and picnic area that has bamboo shacks built out over the water that people can rent out for eating and whiling away the day. Itâs generally a weekend get-away spot, which means itâs nice and quiet during the week.. There are all kinds of food and drink stands that sell everything you need for a picnic along the lake. Close to the lake, there are two Angkorian era temples, Ta Prohm and Yeay Peau, both of which offer some interesting bas-reliefs in fairly good condition. The temples were built under Jayavarman VII in the late 12th century during the same period that Bayon and Angkor Thom in Siem Reap were constructed. Often combined with a visit to Phnom Chisor a bit further down Route #2. The turnoff road to the Tonle Bati area is near the 35km road marker. Buses depart for Takeo every hour. Get off at Tonle Bati and take a motodup to the temples.
