Gläser-Berg, Mountain summit in Thuringia, Germany.

Gläser-Berg is a mountain summit in the Rhön range that rises to approximately 670 meters and overlooks the Felda valley below. The peak sits within a broader mountain landscape shaped by natural slopes and open vistas across the surrounding terrain.

In 1879 the Rhönklub built the first log cabin beside the summit cross; it seated 30 people and was inaugurated on 17 August 1879. A successor building replaced it on 22 August 1914, and the Rhönklub's Dermbach branch rebuilt the cabin, inaugurated on 3 October 1994. In 1998 its roof was newly covered with 35,000 larch shingles.

The summit is marked by the Dermbacher Hütte, a log cabin run by the Dermbach branch of the Rhönklub. A first blockhouse was inaugurated here on 17 August 1879, seating 30 people; it was replaced on 22 August 1914, and the present hut was rebuilt and inaugurated on 3 October 1994. In 1998 its roof was newly covered with 35,000 larch shingles.

A road from Brunnhartshausen leads up to Föhlritz, where a car park sits at the top end of the village; from there a fairly easy path of about 1 km reaches the summit and the Dermbacher Hütte. Föhlritz is served on weekdays from 7 to 19 and at weekends from 10 to 17 by the on-call village bus, line 132 of Wartburgmobil, stopping at the village entrance, about 1 km on foot from the top. A path from Dermbach climbs the north side past the Karl-Friedrich-Stein and the Hirtentränke.

The 1879 wooden blockhouse beside the summit cross was replaced in 1914; the Rhönklub rebuilt it in 1994 and re-roofed it with 35,000 larch shingles in 1998. The Dermbach branch still runs the hut, open Sundays and holidays from 10 to 17.
