Guanella Pass

Guanella Pass Scenic Byway

Guanella Pass passes through two national forests on it’s way from I-70 to US 285. It begins in Georgetown in the Arapaho National Forest and climbs to 11,669 feet in 12 miles.

After the summit, it crosses into the Pike National Forest, before ending in Grant. It’s breathtaking the whole way and definitely worth a trip, which takes about an hour.

September and early October are two of the most popular times to drive the pass, with beautiful fall foliage everywhere. Both sides of the pass offer something unique, with plenty of forests and mountains to explore.
