The hike starts from the highpoint of the "Scharnitz to Roßloch via the Kastenalm" bike ride, and there are plenty of trees to lock your bike to before setting off. There isn't much chance of your bikes getting stolen while you're up at the Karl Schuster bivouac hut, but if you were unlucky and they did go missing, you'd have almost 20 kilometres of "bonus" hiking on which to consider your bad luck!

The river where you swap from bike to foot is the last water source available so - unless the hut has snow close to it which you can melt - you'll need to stock up on enough water to keep you going until you return to the bikes. In the height of summer, when the area around the hut is bone dry, that will likely involve carrying around 5 litres of water per person.

Set off hiking by following a clear, rocky path east which leads you away from the riverbed and then, after about 20 minutes, back to it. Cross over the riverbed and then climb a steep, rocky path up through trees and to the foot of the huge bowl which houses - at its high point - the Karl Schuster bivouac hut.

After leaving the trees the path becomes less and less clear - you'll need to a keen eye for red paint marks and a good nose for micro route-finding if you are to stick to the exact line shown here. Luckily the terrain is pretty similar everywhere around the trail so if you lose it but are heading in the right general direction, you should be fine.

The hut appears on the horizon as you enter the upper part of the bowl, and it should provide the motivation required to get up the final steep slog. Upon arriving, unbolt the door and get settled in! The whole situation of the hut is utterly breathtaking and incredibly peaceful. Enjoy a quiet night in one of the most remote huts in the Alps.
