The hike leads from Crissolo, the last township in the Po Valley, to the source of the largest Italian river, the Po River in Piedmont. The source is located at an altitude of 2020 meters on a plateau of the Monviso Mountain, the Pian del Re.
It’s a relatively easy tour along the river through forest and across meadows. The crystal clear Po River jumps downhill over sticks and stones. The tour leads relatively easy uphill through a piece of forest.
A small detour on the way brings you to the Grotta di Rio Martino which is easy to explore without special equipment. You only need a good torchlight.
You can take a break at the Pian della Regina Refuge serving tasty mountain food.
On the second part of the route it gets steeper. You will find many tributaries that feed the Po. And finally, when you arrive at the plateau Pian del Re, you discover the official source of the Po River.
