The Reserve of St. Antonio Valleys, on the eastern edge of the Orobian Alps, extends for 222 hectares along the valley bottom of Val Brandet and Val di Campovecchio, furrowed by the homonymous creeks, joining in the centre of St. Antonio in the Municipality of Corteno Golgi. The optimal environmental conditions and the good care of the Park area attract an abundant alpine fauna and the birth of precious rare flowers.
