Felsenegg (el. 804 metres (2,638 ft)) is a vantage point in the canton of Zürich in Switzerland.
Felsenegg is located some 7 km (4 mi) in the southwest of the city of Zürich on the Albis chain, between the municipalities of Stallikon and Adliswil. The hilltop station of Luftseilbahn Adliswil-Felsenegg (LAF for short or commonly called Felseneggbahn) aerial tramway is situated on Felsenegg. The Albis area is one of the most important recreation areas of greater Zurich. The area is mostly wooded, but also has extensive fields, often reaching to the summit, some cultivated, some used as pastures for cows or sheep.
Being nearby the city of Zürich, the area is heavily visited. Felsenegg includes a restaurant located at the summit overlooking the Sihl Valley and Lake Zürich to the east, and Reppisch valley, Türlersee and the so-called Säuliamt (District of Affoltern) to the west. Well maintained hiking trails from Uetliberg and Uetlibergbahn mountain station to the north, and from the Albis Pass to the south are highly frequented. Türlersee (Lake Türlen) and Säuliamt are popular hiking destinations, too, as well as a mountain pass and a trail, built between 1908 and 1912, heading for Adliswil respecitively Hausen am Albis. Among other touristic attractions is the Planet trail (German: Planetenweg) near Uetliberg Kulm.
Another landmark is the Felsenegg-Girstel TV-tower located nearby the Felseneggbahn mountain station. It is owned by Swisscom and generally not accessible by the public. The tower was built in 1959 for broadcasting of radio and television programs.
