In reply to JGY:
The route out to the road from the Weisbadner hut is OK. I have done it in very poor viz after a 1m snow dump so had to break trail all the way down. There was a line of posts to follow and in good conditions there is probably a good track to follow as this is the supply route to the hut. Like all those narrowish valleys in that area it is avalanche prone from slopes above but never steep enough at the valley floor. The skate across the lake to Bielerhohe is fine also.
The problem we had was on arriving at the Bielerhohe the road back to Galtur was very avalanche prone from above so we had to descend into Partenen. Under stable conditions you can just ski down the road.
