Hármashatár-hegy is the name of a mountain in the city of Budapest, Hungary. Its name comes from the fact that the borders of 3 cities met at this point in the 19th century. Today, these cities have merged into Budapest, but the mountain's name has remained unchanged. However, the border between the II and III districts still bisects the mountain.
The mountain is located on the Buda side, at 495 m above sea level. The mountain is a popular place for hiking, biking and paragliding. In the winter it is also a place for sled riding. There are several trails in the area, but the only one that reaches the top is the blue trail, also known as the Country Blue Trail. At the summit there are television and radio towers, as well as a restaurant.
