Koitsche, Mountain summit in Bertsdorf-Hörnitz, Germany.

Koitsche is a forested hill of phonolite rising to 375 metres on the southwestern edge of Hörnitz, about seven kilometres from Zittau. Its eastern slope was quarried for stone from the first half of the 19th century, and the disused quarry wall remains visible. A mountain restaurant with rooms stands on the summit.

A first shelter, called a Schenkhaus, stood on the summit from 1833 to 1838; it was later replaced by a simple Schutzhütte. In 1882 a spacious restaurant was built above the quarry wall on the eastern slope, where phonolite had been quarried since the first half of the 19th century. The quarry is now disused.

The mountain inn at Koitsche serves as a gathering place where visitors enjoy regional dishes and local hospitality. This tradition reflects how local communities have long valued the summit as a social and culinary destination.

The summit can be reached via well-marked hiking trails starting from multiple points in the surrounding area. Once at the top, visitors will find orientation aids and a functioning inn where they can rest before or after their hike.

The site merges protected natural monument status with an operational inn and modern lodging facilities directly at the summit. This unusual combination allows visitors to enjoy the landscape while accessing comfortable amenities without leaving the peak.
