Boreas Pass
A gravel mountain road built along the roadbed of a 19th-century narrow-gauge railway, crossing the Continental Divide. Aspen groves turn gold across the hillsides in autumn.
The pass sits at about 3,499 meters. The old narrow-gauge railway once climbed over it to connect to South Park basin. Today it is a gravel road that ordinary vehicles can drive. From town to the pass is about 16 kilometers, and along the way you can see the railway water tower and a restored station cabin on the summit. The aspen groves are most beautiful in late September when they turn yellow, and the route also suits mountain biking. In winter, sections of the road are closed, so the only way up is by snowshoe or cross-country skis.
