Stepin Lug can be divided into several areas:
- Stepin Lug ("Stepa's Grove"), in the northern section of the wood. Bounded by the small street of the Zavojnička reka, it is located in the municipality of Zvezdara. It occupies the small hill of Stražarska kosa and two smaller sub-areas of Baba Velka and Dugo bilo.
- Gaj or formerly Titov Gaj (Tito's Grove), in the central section. It occupies the area of the hill of Golo brdo, between the creeks of Bubanj Potok and Kamena voda.
- Lipovica (Lime tree wood), in the northern section, the least forested area of Stepin Lug, along the Kružni put. It should not bee confused with the much more popular recreational area of Lipovica (Lipovička šuma) in the municipality of Barajevo.
