This is a reverse of one of the local classic hikes, takes about 6 hours, up 1080 m, down 600 m. This is no hike for beginners.

There will be a a restaurant on the way, but bring your own food as well as enought to drink, adequate clothing and good shoes.

I would like to take the 16:20 bus back from Passwang, which should get us to Basel at 17:23.

This means we have to take an earlier train, leaving Basel at 9:06 on track 16, arriving in Zwingen at 09:27 and Erschwil at 09:48.

I will board the train in Dornach, so we will meet in Zwingen.
