Brotjacklriegel, Mountain summit in Bavarian Forest, Germany

Brotjacklriegel is a 1,011-metre mountain in the Bavarian Forest, in the Freyung-Grafenau district. Its summit carries a 27-metre shingled wooden observation tower built in 1924 and opened on 29 June 1925, alongside a Bayerischer Rundfunk TV and radio transmitter. The tower has been closed to climbers since late 2022 under fire-safety rules.

The first observation tower was built in 1839 by a parish priest and two local innkeepers from the village of Langfurth who sought to make the summit accessible to visitors. This early initiative established the mountain as an important destination in the region.

The name likely comes from a surveyor's misunderstanding of the Bavarian "Broada Jaga-Riegl" (Broad Hunter's Sill) as "Brotjacklriegel" during French surveying under Napoleon; a legend instead credits a baker, Brot-Jackl, who hid on the mountain in the Thirty Years' War. The mountain is the symbol of the Sonnenwald region, which comprises Schöfweg, Zenting, Innernzell, Grattersdorf and the market of Schöllnach.

A two-kilometer trail winds from the Jackl parking area to the summit and includes ten educational stations describing the local forest and wildlife. The path is well-marked, the ascent takes roughly an hour, and the stations provide convenient stopping points along the way.

The 27-metre viewing tower, shingled and opened on 29 June 1925, replaced an open frame tower of 1912 that was closed as unsafe after a few years. Climbing it has been barred since late 2022 under fire-safety rules, so the Bayerischer Rundfunk transmitter beside it is now the only structure in use at the top.
