Schiermonnikoog is an island, a municipality, and a national park in the northern Netherlands. Schiermonnikoog is one of the West Frisian Islands, and is part of the province of Friesland.The island is only 16 km long and 4 km wide and is the site of the Netherlands' first national park. The only village on the island is also called Schiermonnikoog. Just under 1,000 people permanently reside on the island, making the municipality the least densely populated in the Netherlands. Because the island is small and flat, only 200 islanders have taken out the special licence allowing them to keep their own car, with the result that the few streets are virtually car-free.
The main source of income on Schiermonnikoog is tourism. The island houses a campground, a ferry pier, a tidal harbour for small vessels and approximately 15 hotels and hundreds of vacation houses and apartments. The eastern part of the island forms an important nature reserve, with access very restricted during the breeding season of the many birds that nest there. The island as a whole is one of The Netherlands national parks, Schiermonnikoog National Park.
