B04 - Castiglione - Erbalunga

At the beginning of Castiglione, at the crossroads along the Strà Granda (B00), the path begins that goes from Drocala to Alpe Prer and then to Alpe Aloro and ends on the Colma ridge in Erbalunga.

Covering just 4.0 km, this is a gentle outing perfect for families or beginners. Allow roughly 53 minutes.

This linear trail moves from one end to the other without looping back. A return journey by transport — or retracing the path — is needed to get back to the start. Follow the B04 waymarkers throughout to stay on the official trail line.

As a Local Walking Network (LWN) route, this trail has a strong community character. It serves both regular local walkers and visitors discovering the area for the first time.
