The nature park covers the eastern half of the natural region of the High Taunus. This is where the main ridge of the Taunus runs with the highest peak in the range, the Großer Feldberg (881.5 m). Also part of the park and north of this ridge is the much larger Eastern Hintertaunus. Another part of the park is the Anterior Taunus, a narrow strip south of the ridge that descends to the Rhine-Main Plain. The original name of the park, High Taunus, was thus not really accurate.
