The nature in Færder National Park has been shaped by human activity for thousands of years. Traces of permanent settlements, fishing, small-scale farming, shipping, war, and abandonment can be seen everywhere. At the same time, the area has a very diverse flora and fauna. Plants and insects that are hardly found elsewhere live here.
Færder National Park covers 340 square kilometers of mainland, islands, islets, and seabed in Tjøme and Nøtterøy municipality. It stretches from Ormøy in the north to Færder lighthouse in the south. The islands south of Hvasser, Verdens Ende - “The world's end”, and Moutmarka are included in the national park. In the middle of the Oslo Fjord, Færder National Park borders Ytre Hvaler National Park.
