There are two separate Parking lots, the one behind the Thöni factory is mainly for the sector Sunshine Raggae. All sectors can be reached from both parking lots its just a question of proximity. The main Parking lot ist closest to all sectors except for Sunshine Raggae.
From the main parking lot follow the red GPS trail, all the sectors will be to the right off the wide path. Look for the big yellow signs and you won't miss it.
Hängebrücke is at the end of the wide path, walk over the bridge and then down into the riverbed. From here you can also get to the sector Sunshine Raggae by walking down the Klamm.
