From Altdorf drive to Silenen (road 2) and there take exit 38 to Amsteg. At the end of the exit go right to Birsten. At a small power station go left after the bridge, there is small sign Maderanertal/Bristen. The road ends at the cable station Golzern (Birsten). Park your car here (gps 46.766249, 8.712342).

It is also possible to book an Alpentaxi (>two days in advance) that goes deeper into the valley, as far as Hotel Maderanertal. It is not cheap, in the year 2018: CHF 60.
