Hohe Asch, Mountain summit in Lipper Bergland, Germany.

Hohe Asch is a 371.5 m high summit in the Lipper Bergland, about 2 km southeast of Bösingfeld in the municipality of Extertal. Its eastern part is wooded, and a 15 m concrete observation tower has stood about 100 m west-southwest of the summit since 1980. A trigonometric point at 366.3 m lies roughly 85 m west of the tower.

The concrete observation tower was built in 1980, marking an important step in making the summit accessible to the general public. This construction allowed the location to develop as a popular destination for day visitors.

The mountain serves as a junction for multiple hiking routes, including the European long-distance trail E1, linking nearby communities through outdoor recreation. Visitors encounter different paths that crisscross the area and connect the surrounding landscape.

The mountain is best reached via Kreisstraße 57, which runs westward from Bösingfeld through Hummerbruch to Alverdissen. Visitors should wear sturdy footwear since the hiking routes across the slopes present varying terrain conditions.

The 15-metre concrete observation tower, erected in 1980 about 100 metres west-southwest of the summit, allows views of the Kaiser-Wilhelm-Denkmal near Porta Westfalica, the Köterberg, the Eggegebirge, the Teutoburger Wald with the Hermannsdenkmal, and on clear days the Brocken in the Harz, 1141 metres high.
