The Büchelstein is a mountain, 832 m above sea level (NN) high, in the southern Bavarian Forest near the higher peak of the Brotjacklriegel.

Its forested slopes rise above the bowl of the Lallinger Winkel in the east and the village of Grattersdorf to the north.

Just below the highest point is a lookout rock with a large summit cross and wide panoramas over parts of Lower Bavaria.

In föhn conditions in autumn even the northern chain of the Alps may be seen from the Dachstein to the Zugspitze.

In addition there is a starting point here for hang gliders, that take off in suitable right thermal conditions.
