It covers the region of eleven rings around Oberwald, the central part of the mountain range, certain municipalities in the counties of Vogelsbergkreis, Wetteraukreis, Gießen and Main-Kinzig-Kreis.
The park has an area of 883.36 km² and is thus roughly as large as the capital city of Berlin.
The nature park is characterised by mixed forest, grassland and wetland biotopes as well as a raised bog.
The German holiday route from the Alps to the Baltic runs through the middle of the park.
The High Vogelsberg has cultural-historical significance as a result of the fairy tales of the Brothers Grimm.
