The shortest ski tour ascent on Brennkogel is from Elendgrube, the parking place north of Hochtor saddle. As this side of the mountain is rocky, you need to cross the whole southern slope, but you lose almost no height on this tour. The best time to do this tour is spring season, when the road over Hochtor is already opened and when there is no big avalanche risk below Brennkogel-Scharte.
The ski slopes above Brennkogel-Scharte
You park on the road, north of Hochtor, on the altitude of 2375m. Crossing the eastern slopes of Brennkogel you ascend on skis towards the SW. Soon the slope below Brennkogel-Scharte becomes steep, but in good conditions you can ascend the notch with skis. On the othes side you first descend a few meters, but soon you are able to start crossing the southern slopes of Brennkogel slightly upwards. You do the crossing until you reach the broad slopes below Brennkogel's West ridge. Now it's time to go directly upwards. Again the last meters below the ridge are steep, but as the whole slope is not expose you will have no problems with the ascent. The western ridge and the summit cone is rocky and snow is often blowned away from the slope. Still it's common to ascend the very summit carrying skis and later skiing down between rocks. In any case there are no technical problems.
You can ski down by the ascent route, but if you have in the group a driver-victim, other members can ski down towards the south and do the whole slope to the altitude of some 1100 meters (to Guttal Bach bridge), where the driver picks you up.
Only a usual tour-skiing equipment.
