On top of the forested mountain, which is a well known and popular recreation area, are the Emperor William II Tower, which offers views over the Rothaar highlands, the Biedenkopf Transmitter and a ski lift.

The Sackpfeife rises in the southern Rothaar Mountains in the western part of the state of Hesse on the border between the counties of Waldeck-Frankenberg to the north and Marburg-Biedenkopf to the south.

Although the Sackpfeife is not one of the highest mountains in the Rothaar, whose summits reach 843.2 m, it towers prominently above its immediate surroundings and has a topographic isolation of about 8 km.

Because the summit region is extremely wide in the direction of the range (north-northeast) its highest point lies clearly within the parish of Hatzfeld and thus in the county of Waldeck-Frankenberg, but, for example the site of the Biedenkopf Transmitter is in the borough of Biedenkopf at a height of 665 m, just under that of the main summit.

The Sackpfeife is accessible by car on a no-through road between Hatzfeld-Eifa and Biedenkopf that branches off the Bundesstraße 253.
