Colorado's mountain passes and byways become golden corridors each fall as millions of aspen trees change color. Scenic drives offer the most accessible way to experience the spectacle - no hiking required, just stunning views from your car window.

Peak color typically occurs late September to early October, moving from higher elevations down. The best drives pass through aspen groves between 8,000 and 11,000 feet. Mix in evergreen contrast, dramatic mountain peaks, and Colorado's famous blue skies for unforgettable scenery.

Popular routes get crowded on fall weekends. Start early - trailheads and pullouts fill by 8 AM on peak color Saturdays. Weekdays are significantly less crowded. Many passes close for winter in mid to late October, so time your visit carefully.
