Langli

Langli is a tidal marsh island in the Danish Wadden Sea near Esbjerg. It stretches roughly 0.8 kilometers in length and is connected to nearby Ho by a 3-kilometer causeway that is accessible only at low tide.

The island was permanently settled in 1840 by two families who built dikes and developed agricultural activities. By 1911, the population had grown to about 38 residents.

Langli is Denmark's last remaining hallig, a special type of tidal island without protective barriers that shapes the Wadden Sea coastal landscape. Visitors who reach the island can see how this distinct settlement form has left its mark on the terrain.

Access depends on tidal conditions and is subject to seasonal regulations. Public visits are only permitted between mid-July and mid-September via the causeway.

The former mansion on the island now operates as a research station, run by the Danish state since 1982. This repurposing enables scientific studies of the Wadden Sea's unique conditions.
