Demeljoch, Mountain summit in Tyrol, Austria.

Demeljoch is a mountain summit in the Northern Limestone Alps on the border between Bavaria and Tyrol. The peak sits at 1,924 meters (6,313 feet) elevation where the two regions meet.

The ridge's three summits, including the 1,924 m Demeljoch, lie on the Bavaria–Tyrol border. Near the Demel-Hochleger stands boundary stone No. 209, dated 1557, marking that old line. The stone is the concrete relic of the border, not a marker on the summit itself.

The Demeljoch stands as part of the North Tyrol Limestone Alps within the Karwendel Nature Park, representing Alpine geological formations in Central Europe.

The main route starts from the village of Fall (773 m) above the Sylvenstein reservoir; the tour is rated easy and leads over the ridge to the 1,924 m main summit. The state border between Bavaria and Tyrol runs north to south across the summit, so carry a passport or ID.

Near the Demel-Hochleger, close to the ridge, stands boundary stone No. 209, dated 1557. The three-summit ridge also carries the Dürrnbergjoch (1,835 m) and the Zotenjoch (1,881 m) alongside the main summit. The state border between Bavaria and Tyrol runs north to south across the summit itself.
