Stargazing, seals and sandbanks in MandøDenmark’s wilderness zones and sparsely populated isles have long been havens for nature lovers and stargazers. Mandø, on the south-west coast of Jutland, is the most recent addition to the country’s four Dark Sky Parks. A small island in the Wadden Sea National Park, Mandø is most easily accessed at low tide via tractor bus over the causeway from the mainland – adding to the adventure and reducing the chances of latecomers’ annoying car headlights ruining your night vision. By day, you’ll likely want to visit the lovingly preserved, thatched and white-walled Mandø House museum (an early 19th-century shipmaster’s home), not to mention the island’s landmark windmill and church. Observe thriving seal and migratory bird species on a bike ride around the marshes and sandbanks.
