“A short path traverses the val Breggia between Castel San Pietro and Morbio Superiore.”
— Lost Justpastnowhere
This is a short, mostly singletrack path that runs through a forested area near the Torrente Breggia (stream) which connects the cities of Castel san Pietro and Morbio Superiore. From the bridge over the river Breggia, you've got a nice view upriver. There is a short section that will require carrying the bike where the trail has been washed out and rerouted.
The trail lies within the Parco delle Gole della Breggia (Park of the Breggia Gorges), which preserves some interesting geology, including a waterfall, and historical buildings (mills, castle) in the val Breggia (valley).
