Scenic pass that is opened all year round (closes at 6pm in winter). There is hardly any traffic which makes cycling very nice and plenty of opportunities to take pictures. We crossed the pass in early May when there was still plenty of snow up there. The change in scenery where it was all green at Disentis and slowly turning white as we climbed higher... and very quickly turned to green as we rolled down on the south side to Biasca was breathtaking.

A great starting point for hikes from Airolo. The trains are reliably punctual, and there are many departures in both directions.
