In reply to Plug81:
Didn't do any Via Ferrata but there's some relatively low grade climbs at Riffelsee- you can pay 30F & get the train up & hike back down. Amazing views of Matterhorn at around 3500 I think - no issues acclimatising...
We were told it was well equipped! - that meant one ring between anchors, 30-40m pitches (single bull rings as per the old skool style) I had one back up link cam on my harness and a trad rack in my tent.
