fine page from someone who knows what he is writing about.
map to buy is SLK 1:50000 Nr. 248 S Praettigau
recommendation: the trip is nice but a bit short for a full day. I can recommend climbing Hasenflue, 2412m, (perhaps without the rocky summit itself) in addition after a downhill to Alp Saess.
Raetikon Mountain Group should be chosen as parent!
