October is one of the most magical months in Summit County, Colorado. The golden aspens are still clinging to the hillsides, cooler nights bring crisp mountain air, and the first hints of winter start to show at higher elevations. While summer crowds have gone home and ski season hasn’t quite begun, October offers a perfect mix of peaceful outdoor adventures, local festivals, and family-friendly events.
If you’re wondering what to do in Summit County this October, here are the top activities and events to enjoy in Breckenridge, Frisco, Dillon, Silverthorne, and Keystone.
Outdoor Adventures and Fall Colors
Scenic Drives and Leaf Peeping
Early October is prime time for fall foliage in Summit County. For breathtaking views of golden aspens against the Tenmile Range, take a drive over Boreas Pass Road, cruise along Swan Mountain Road, or explore Loveland Pass. Don’t forget your camera—sunrise and sunset are the best times for mountain photography.
Hiking and Biking
Cooler weather makes October perfect for hiking and biking. Trails like the Sallie Barber Mine Trail in Breckenridge or the Old Dillon Reservoir Trail near Dillon are local favorites. Be prepared for variable conditions—some higher elevation trails may already see a dusting of snow.
Late-Season Golf and Fishing
Before winter arrives, you can still enjoy a round of golf at Keystone Ranch Golf Course or cast a line in the Blue River for fall fly-fishing. October is often quieter on the water, making it a peaceful time to fish.
