Alte Bobbahn, Hiking trail in Wernigerode, Germany.

The Alte Bobbahn is a hiking trail north of Schierke in the Harz. It runs from the junction of Edelmannshäuweg and Neuer Weg north across the Brockenbahn railway to the Bahnparallelweg, then on toward the Brockenstraße. A shelter at the Bahnparallelweg crossing has a sign on the former bobsled track, and wall remains lie off the path north of that crossing.

The bobsled track was built in 1907 as a natural track about two kilometres long, starting at the Brockenbett. Competitions, including German and Harz championships, were held between 1908 and 1958. In the mid-1930s it was shortened to 1450 metres, starting on the Brockenstraße at 821 metres and finishing 141 metres lower near Schierke. It was abandoned in the 1950s.

The name Alte Bobbahn keeps the memory of the 1907 natural ice track alive; races between 1908 and 1958 included German and Harz championships, run first with five-man bob teams and later with two- and four-man sleds, as well as skeleton and luge events. A sign at the shelter by the Bahnparallelweg junction explains this history to walkers.

The trail is accessible year-round and well marked, with parking near the starting point. Several rest areas with benches are distributed along the route to allow for breaks.

Plants and mosses grow through cracks and gaps in the old concrete throughout much of the route, giving the track a wild, natural appearance. This contrast between artificial structure and forest reclamation shows how quickly nature reclaims abandoned places.
