Stuifen, Mountain summit in Baden-Württemberg, Germany.

Stuifen is a 757-meter-high hill of the Swabian Alb and the highest of the Drei Kaiserberge, the trio it forms with the Rechberg and the Hohenstaufen. It lies in the municipality of Waldstetten and, unlike its two neighbours, is almost entirely wooded and has no buildings; the summit can be reached only on foot.

Until around 1850 the Stuifen was covered by juniper heath; reforestation for flood protection began afterwards and was completed in 1918. The summit has always been free of buildings, unlike the neighbouring Rechberg and Hohenstaufen, and is reached only on foot. In September 2011 a twelve-metre wooden cross was erected on a clearing at 718 m on the west side, facing the two other Kaiserberge.

The Stuifen is the local mountain (Hausberg) of Waldstetten, and unlike the neighbouring Rechberg and Hohenstaufen it carries no buildings. Since September 2011 a twelve-metre wooden cross stands on an open patch at 718 m on the west side, facing the two other Kaiserberge; a shelter and a barbecue area share the viewpoint looking south and west.

Multiple marked trails lead to the summit from several starting points, with the most direct route beginning at the Rechberg parking area. The path is clearly signposted throughout and requires no special equipment for a typical day hike.

The Stuifen is the highest of the Drei Kaiserberge at 757 m, yet unlike the Rechberg and Hohenstaufen it carries no buildings and is almost entirely wooded. Until 1850 juniper heath covered the summit; replanting for flood protection was finished in 1918. A 12 m wooden cross was raised on the west side in September 2011 at 718 m, facing the two neighbouring peaks.
