Vallone Soustra. We left the car at Grange del Rio and started on our climb to Passo Losetta at 2872m. It leads through Vallone Soustra which is very nice, in good weather certainly even nicer. The weather was a mix of clouds, a little sun and rain. At the pass even a little hale and snow. It was cold, in the last bit to the pass I put on gloves and hat.
