Arresø
Lake Denmark's largest lake and recreational area
Denmark’s largest lake on Zealand, Arresø offers reed-fringed shores, cycling routes and birdwatching hides. Day-trippers paddle, picnic and follow paths linking nearby villages.
Arresø is a freshwater lake on the island of Zealand in the Capital Region of Denmark and is the country’s largest lake by surface area. It lies within a largely rural and mixed landscape of woodlands and agricultural land.
Visitors come for lakeside walking routes, birdwatching and local fishing; the shoreline includes nature areas and small settlements with access points. The lake is part of regional recreational networks rather than a single developed visitor site.
The lake’s modern shoreline and water level have been influenced by drainage works and canal connections over the centuries, including a historic canal that links the lake to nearby watercourses. It has long been a resource for local communities.
Situated in northern Zealand, the lake lies within the Capital Region of Denmark and is accessible from nearby towns such as Frederiksværk and Hillerød.
