Düne

Düne is a small sandy island adjacent to the larger island of Heligoland in the German North Sea, known for its beaches and coastal wildlife. It functions primarily as a recreational and wildlife area rather than a permanently populated settlement.

The island’s shallow beaches and sandbanks attract seals and seabirds, and its shoreline is a common destination for day-trippers from Heligoland and the German mainland. Visitor facilities are limited and focused on beach use, wildlife viewing and short coastal walks.

The island’s shape and shoreline have been reshaped repeatedly by North Sea storms and tides, and human infrastructure such as landing facilities and an airstrip were added in the 20th century to support tourism and transport.

Düne sits immediately off the main Heligoland island in the German Bight of the North Sea and is reached by short boat transfers from the Heligoland harbour or by flights that use the island’s small airstrip.

• Seal colony: A resident grey seal population regularly uses the island's beaches and sandbanks, making wildlife viewing a primary attraction for day visitors.
• Access: A small airstrip and regular boat connections link the island with the larger Heligoland island and with mainland ferry services, enabling day trips for tourists.
