Nice pass with a very nice view! Nice view of the castle (which despite being visibly in ruins is paying for the visit)

Super little pass which is only really steep for its first 5-6 kilometers; the last 8 kilometers alternate between passages in the forest and passages with great views of the surrounding valleys. The surface is good and there is very little traffic.
