The small town Duba is located at the east border of the Kokorinsko national park in the North Bohemia, southward of the town Ceska Lipa. The town is well-known thanks to the nearby recreation centre the Machovo lake. Two important cycle trails cross the town. The first goes from the town Most via the Machovo lake to the town Doksy. The second one leads through the beautiful area of Kokorinsko. There is a camp by the Cerny lake very close to Duba. If you are tourist fans, you will meet many bunkers from the Second World War set close the tourist paths.
