Eastern classics
Great Smoky Mountains, Shenandoah, and Acadia peak across October by elevation, higher first.
Cades Cove and Skyline Drive on October Saturdays are among the year's worst crowd days.
Aspen gold in the Rockies
Grand Teton and Rocky Mountain turn in September. Weekdays reward photographers at Oxbow Bend and Trail Ridge approaches.
Check foliage reports
State forestry and park webcams help. Peak rarely matches the same weekend every year.
Drive timing
Sunrise and sunset drives beat 11 a.m. to 3 p.m. for light and traffic. Have a rainy-day museum plan in gateway towns.
Alternatives when leaf weekend scores high
Capitol Reef and Grand Canyon south rim offer color and geology without Smokies-level leaf traffic some weeks.
Use elevation to rescue an imperfect foliage date
Color moves downhill. In Great Smoky Mountains, high ridges can turn before Cades Cove; in Shenandoah, the 105-mile Skyline Drive spans enough elevation and distance to find different stages on the same day.
If a report says peak has passed at one overlook, try a lower valley rather than joining a traffic queue at the best-known stop. NPS reports and webcams are better than a fixed annual calendar.
