Buresø

Buresø is a lake located in a tunnel valley, immediately southeast of Slangerup, where Allerød, Frederikssund and Egedal municipalities meet. The tunnel valley, which was formed during the last ice age, runs in an east-west direction and can be followed along Mølleåen all the way to the Øresund coast. Between Buresø and the nearby Bastrup Sø there is a watershed. Buresø drains via Græse Å to the west to Roskilde Fjord, Bastrup Sø drains to the east to Mølleåen. Buresø and surroundings is part of Naturpark Mølleåen.
