The Hármashatár Mountain is the best hiking place in Budapest which is not as crowded as the János Mountain. You can find here the Guckler Károly Viewpoint which was built in 2016 and this is the best place for seeing Budapest from the top.

You can see Budapest from the top, enjoy nature and a good hiking. At night the view is even more spectacular so it deserves a visit. The atmosphere on the mountain is really good and you can get some fresh air.
There is a restaurant on the mountain if you would like to get a nice snack or lunch.
