Denmark Skjern Enge Pull Ferry

Near Lønborg, east of Ringkøbing Fjord, is Denmark's largest river delta: Skjern Enge. Hikers and cyclists obviously make intensive use of the paths marked here.
A pull ferry (Trækfærge) for up to 12 people crosses each of the two main arms of the river.
North the northern ferry, there is "Pumping Station North" (signposted) with a viewing platform on the roof of it. Swallows buzz around here, they have built nests in many places on the building.
