Rotbühelspitze, Mountain summit in Silvretta Alps, Austria.

Rotbühelspitze is a mountain peak in the Silvretta Alps standing at 2,852 meters. Its western side features steep slopes and exposed rock, while the surrounding terrain transitions gradually toward the valleys below.

The Rotbühelspitze forms the main summit and namesake of the Rotbühelspitzgruppe, a subgroup of the Silvretta on the border between Vorarlberg and Graubünden. The German name Rotbühelspitze and the Swiss Rotbüelspitz both refer to the same peak, which rises between the Montafon valley and the Prättigau. The summit stands at 2,853 m above sea level on the Austrian side and 2,851 m above sea level on the Swiss side.

The mountain gives its name to the Rotbühelspitzgruppe, the group of peaks around it, and is its main summit. The border between Vorarlberg and Graubünden runs over the top, so a climb crosses from the Montafon side above Gargellen to the Prättigau side above Klosters. The route through the Wintertal is described in ski-touring guides as a classic of the Silvretta.

The usual route starts at Vergalda, a hamlet of Gargellen in the Montafon, and climbs through the Wintertal valley to the summit; the tour is given as 4.5 hours in both summer and winter. It is above all a ski tour, so winter parties need avalanche assessment and equipment for steep snow.

The summit is the highest point of the Rotbühelspitzgruppe, the subgroup of the Silvretta that takes its name from the mountain. The slightly higher Isentällispitz lies just to the south, so the two are often climbed on the same day.
