Molas Pass is the last mountain pass of the Iron Horse Bicycle Classic, a race in which cyclists ride from Durango to Silverton against the Durango and Silverton Narrow Gauge Railroad's steam train. Riders who reach the pass have climbed most of the course's final ascent before the descent into Silverton.

The road is open year-round, but winter tires or snow chains are a good idea from October through April. Checking road conditions before you set off is always worth doing, particularly after heavy snow or during unsettled weather.
