With a surface area of 43.7 km2 (16.9 sq mi), it is the third largest district in Warsaw, comprising 8.6% of the city.

The eastern section of Ursynów is heavily built up with blocks of flats, while its western and southern sections are often referred to as Green Ursynów due to its lower population density and broad open spaces and green areas.

Ursynów's southern extremity comprises Kabaty Forest, covering more than 9.2 km2 (3.6 sq mi).

Other popular attractions include the Vistula river escarpment, Natolin palace and Służewiec horseracing track (built in 1939), used not only for its original purpose, but for open-air exhibitions, pop concerts, etc.

There are two nature reserves in the district: Stefan Starzyński Kabacki Forest and Skarpa Ursynowska.
