Piz Buin can be reached from the Wiesbadener hut, crossing the Vermunt glacier, climbing up the Wiesbadener ridge and hiking over the Ochsentaler Glacier to the Buin gap. From the gap there is a zigzag walk to the top, with only a 20 m (65 ft) steep step to surmount before reaching the relatively flat summit space, which has an old wooden cross on the very top. The border between Switzerland and Austria crosses the summit from East to West.
