Flasken

Flasken is a small brackish-water lagoon and a designated natural protection area on the western coast of Zealand, Denmark. It lies where the Halleby Å river reaches the Jammerland Bugt in the Storebælt, forming the northern boundary of the low sandy tongue that connects the former island of Reersø to the mainland. Together with Reersø Vejle to the south, Flasken belongs to a single conservation area of 285 hectares that was formally protected in 1979. The site is valued for being one of the last unregulated river mouths remaining on Zealand, where freshwater from the inland Halleby Å system meets the saline waters of the Great Belt. Its position at the interface between a large river catchment, coastal lagoon, and raised beach ridges gives it a distinctive transitional ecology that has been incorporated into a broader Natura 2000 habitat area and the surrounding Naturpark Åmosen. Flasken's significance is closely tied to the long-term coastal reshaping that turned Reersø from an island into a tied landmass, with successive beach ridges gradually steering the river southward to its present outlet.

Distance methodology

Geographic measurements, not driving distances

How nearby park distances are calculated

Distances use park boundaries whenever the available geometry allows it. When one or both boundaries are missing, the mapped park locations provide a clearly labelled estimate. Every value represents straight-line geographic separation and does not use roads or routing.

Boundary distance

Calculated between the nearest points of both park boundaries.

Location-to-boundary estimate

Estimated from one mapped park location to the nearest boundary of the other park.

Mapped-location estimate

Estimated between the mapped locations of both parks.
