Alpe in Val d'Ossola at 1088m a.s.l., starting point of the ski resort of Domobianca. In summer the ski slopes turn into downhill trails. There is an adventure park.
Trail is NOT S1. More like S3 most of the way. If you can't ride solid S2/S3 be prepared to spend more time walking then riding. Quite nice Trail. Everything is rideable.
