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.

Because of the many tunnels, you should definitely have lights (which are mandatory anyway) mounted on the front and rear of your bike when riding over the Lukmanier Pass.

The Lucomagno is one of the most famous Alpine passes in Switzerland. It is located between the cantons of Ticino and Grisons, at an altitude of 1,926 meters. The name seems to derive from the Latin "locus magnus", meaning "large, open place". It is often tackled in the professional race of the Tour of Switzerland.

The only disadvantage is the numerous tunnels. For example, there is a 2 km avalanche gallery along the lake at the summit, which blocks the view. But it is a pleasant climb.

From Disentis up the Val Medel to the Lukmanier Pass – a dream 🤩. Except for a few short exceptions, the road is very easy to ride with a gradient of around 5%. The long valley offers wonderful views in all directions and, despite the lack of hairpin bends, is a lot of fun to ride.
