San Bernardino Pass (South side)

The San Bernardino Pass serves as a breathtaking gateway from the Italian-speaking Misox Valley to the Hinterrhein in Grisons. Historically, it has been a vital artery through the Alps for centuries, with the Romans first carving paths through its rugged terrain. However, its true golden age of commerce began in the early 19th century when the "Strada Commerciale" was constructed, transforming the pass into a sophisticated engineered route for horse-drawn post coaches. Today, while most transit traffic is swallowed by the 6.6 km road tunnel below, the high mountain road remains a preserved relic of Alpine heritage, winding past the crystalline Lake Moesola at the summit. For cyclists, the south side ascent from Mesocco is a masterclass in rhythm and scenic progression. It’s a demanding but rewarding climb that gains approximately 1,300 meters of elevation over 24 kilometers. The initial ramps are punchy, but the experience truly transforms as you hit the iconic switchbacks that dance through pine forests and eventually break into a desolate, lunar-like plateau. Because through-traffic prefers the tunnel, the asphalt is often eerily quiet, allowing riders to focus on the steady 8% gradients and the dramatic views of the Adula Massif.
