Palazzago, Linzone, Roncola (discesa infinita)
A nice ride with excellent views, and a pretty tough descent. You go up from Palazzago via the Italcementi quarry. I don't know if you can pass while they are working during the week, someone told me they don't say anything but as a group I recommend passing only on weekends. After the quarry almost all rideable trail to the Linzone cross.
(As soon as I get a chance I'll put some less "white" photos).
From the cross to Roncola is an initially S1 descent but quickly evolves into S3, the rock tends to be slippery so I recommend waiting for dry periods. From Roncola following the trail the level is S1/S2 with some short more challenging passages towards the final part
MTB: Yes
EMTB: Yes
Difficulty ascent: always manageable
Difficulty descent: S3 first part; S2 from Roncola
Drainage: Not much, wait for dry period.
