The Buda Hills are one of the greenest areas of the city, and are very popular with Budapest citizens who want to take a little time away from city life.
There are various hiking trails to follow and mountain bike paths as well, which range from easy to medium level of difficulty.
For those who want to explore the hills in a more leisurely fashion, visit the Children’s Railway, which is entirely staffed by children aged 10-14 (with the exception of some adult staff who are responsible for safety).
