Climbing Independence Pass eastwards from Aspen is a bucket-list journey to the Continental Divide, reaching an extreme altitude of 12,095ft, making it one of North America's highest paved passes. Prepare for a very long 18-20 mile and challenging climb gaining over 4000ft; while the average grade is moderate at 4-5%, expect long, sustained climbing sections particularly above the tree line, likely averaging 6-8% in parts, amplified significantly by the thin air. Along the route you'll see the stunning transition through beautiful aspen groves to breathtaking alpine tundra vistas. Be aware that services are non-existent between Aspen and Twin Lakes so be self-sufficient and check the road status before attempting the climb.
