Last week I made 2 LMHW trail itineraries:
40 Passo del Rastrello - Valico of Casoni
41 Valico of Casoni - Alpicella
and I'm trying to put the related traks on osm.
After a bit of unofficial tests with other tracks ... I hope to be able to make it good ... I know that being the first time ... I will certainly need some help .... from Ale_Zena for example who started me on this Osm adventure...

The itinerary has gone further HW mountains reaching Zignago, the Zum Zeri ski resort in the Emilia Region, and Montereggio in Tuscany
