The Börzsöny hills are north of Budapest in the area of the Danube bend. Lots of weekend houses out here. Endless supply of forest fun: lots of trees, small streams, mountain vistas, Büfé in the middle of nowhere… good times. Take the train to Szob from Nyugati train station and get off at Kismaros. You will be greeted by a fully stocked CBA store, bar, bufe and lots of icecream!
