Helgoland, a mesmerising German island can easily be missed as it is barely 2 km long and only 56 m above sea level, as you sail through the North Sea. Part of a tiny archipelago 50 km out from the River Elbe, the mostly grassy plateau surrounded by jagged red sandstone cliffs was a wartime naval base.
Helgoland is now a holiday getaway, visitors come for windswept walks and birdwatching. The town of Helgoland was rebuilt following wartime destruction – take a tour of the Festung Helgoland war tunnels.
