Haderslev Dam is a long, narrow lake — created by damming the Haderslev stream in the medieval period — that runs through the centre of town and defines its geography. The banks are lined with walking paths, benches, and old mill buildings, and the lake is a genuine pleasure in summer and autumn when the surrounding trees turn.
The path along the lake connects the old town to the surrounding countryside within a twenty-minute walk. Swans and ducks make the lake their permanent home. For a small Danish town, the waterside setting is genuinely attractive, and the combination of the dam, the cathedral rising above it, and the old merchant houses along the bank makes for the best walking in Haderslev.
