Being an ancient township, Tong Li borders on Tongli Lake on the east, Nanxin Lake on the south, adjoins Pangshan Lake on the west, Jiuli Lake on the north and Wusong Jiang River on the northwest. The town proper is divided by the streams into 7 islets interlaced with the surrounding water area, forming typical water county of the south.

With a network of lakes and waterways, Tongli has not suffered from war since it was inaccessible in the old times. Therefore more ancient buildings are preserved, among which we can still enjoy the following scenic spots “ the Moon Viewing at the East Stream”, “the Misty South Market at Dawn”, “the Night Crossing at the West ferry”, “the Spring Sight in the North Hill”, “the Fishermen's Flute in the Water Village” and “the Misty Bamboo of the Chan Hill”. The traditional houses densely settle on the sides of the fine banks piled by Jinshan Stone, and winding alleys and streets paved with pebble stones still keep the ancient appearance. There are 24 bridges at the intersection of waterways. The Siben Bridge built in the Southern Song dynasty is simple and archaic. The Fu'guan Bridge built in the Yuan dynasty is grandiose. 

Tongli is rich in culture. In the long run of its history, it was once famed for its achievements in the imperial examinations and has produced famous cofucianists and notables. About 40 stone tablets of different periods have been well preserved and a quite number of its steets and alleys are named after the official titles such as Zhuang-yuan Street, Tongzhi Street, etc.
