Glaspass is a high mountain pass at an elevation of 1.846m (6,056ft) above the sea level, located in the district of Hinterrhein in the Swiss canton of Graubünden.
The road to the pass is asphalted. The road's winding design, providing stunning panoramic views, is very curvy and fun for a leisurely ride, so it pays to take it slow. Starting from Thusis, at first the road is wide and very good, but the last part is a narrower road with less good asphalt. The pavement runs out shortly after the pass height.
Starting from Thusis, the ascent is 11 km long. Over this distancethe elevation gain is 1.145 meters. The average percentage is 10.4 %. For many centuries the pass between Heinzenberg and Piz Beverin was the most important connection between Thusis in the Domleschg Valley and the remote Safien Valley.
