Großer Buchstein, Mountain summit in Nationalpark Gesäuse, Austria.

Großer Buchstein is a mountain summit in Nationalpark Gesäuse that rises to approximately 2,200 meters elevation. The peak stands out for its significant prominence within the Ennstal Alps region.

On 9 August 1814 the Admont cleric Albert Muchar climbed to the summit with measuring instruments and calculated its height at 1171.7 Klafter (2222 m), two metres from today's official value. Wilhelm Schleicher of Gresten made the first tourist ascent via the west gorge, described in the 1867 yearbook of the Austrian Alpine Club. Empress Elisabeth of Austria reached the summit on 18 September 1885.

The peak's name passed into Berlin street naming when Buchsteinweg in Mariendorf was named after the massif in 1930. On the mountain itself, the Buchsteinhaus at 1546 m below the south wall is the base where climbers overnight before the summit. Empress Elisabeth of Austria reached the top on 18 September 1885, an early tourist ascent still recalled locally.

Several routes lead to the summit, each with different difficulty levels to suit various hiking abilities. The mountain is most accessible in good weather and requires solid hiking experience.
