Fellberg, Mountain summit in Thuringia, Germany

The Fellberg is a mountain of the Thuringian Slate Mountains rising to 842.1 m above sea level west of Steinach. With the 2 m higher Breitenberg to the west it forms a horseshoe open to the south, and just below 820 m separates the two summits. The Fellbergbaude inn stands at the transition to the Geiersberg, amid the world's largest slate quarries.

The summit takes its name from ancient terms for field and mountain, reflecting the rural past of the region. The marked hiking trails are part of a long tradition of walking in Thuringia that extends back to the 1800s.

The Fellbergbaude sits at the saddle between the Fellberg and the Geiersberg, among the world's largest slate (Griffel) quarries. Skiing reached Steinach around 1901, and a ski jump was later built between the mountain and the town; races are still held here because of reliable snow. Since 2005 the slopes host the Silbersattel bike park, Thuringia's first, open for downhill practice each weekend.

Several marked hiking trails lead from different starting points, with parking available at the base for visitors. The walk is possible year-round, though the warmer months offer the easiest conditions for the climb.

Special plant species adapted to the higher elevation grow at the summit, forming a rare ecosystem. These meadows differ noticeably from the forests below and attract visitors interested in local plant life.
