Summit County packs more into a single county than most regions manage across an entire state. Things to do in Summit County Colorado range from world-class skiing and lake recreation to historic Main Streets, trail networks, festivals, and dining – across six distinct communities, in every season. Whether you are planning a visit or considering a home here, this guide covers the full picture.
Best Year-Round Activities in Summit County CO
Eighty percent of Summit County is public land. That single fact explains why things to do in Summit County never run out – the trails, rivers, reservoirs, and peaks that surround every town are publicly accessible year-round. Four ski resorts sit within a 15-mile radius: Breckenridge, Keystone, Copper Mountain, and Arapahoe Basin. In summer, the same terrain opens to hiking, mountain biking, fly fishing, paddleboarding, horseback riding, and golf. The county sits roughly 90 minutes from Denver International Airport, making it accessible for both weekend trips and extended stays.
Things to Do in Breckenridge Colorado
Things to do in Breckenridge Colorado cover more ground than the ski resort alone – the town operates as a full destination in every season, with a walkable historic core, strong dining scene, and a calendar of events that runs year-round.
Breckenridge Attractions for Visitors
Breckenridge attractions cover the mountain and well beyond:
Free gondola – scenic ride over Cucumber Gulch Wildlife Preserve, no lift ticket required
Breckenridge Outdoor Education Center (BOEC) – adaptive outdoor programs making the mountain accessible for people of all abilities
Ullr Fest – ten-day winter celebration each January with games, parties, and a torchlight parade on the mountain
Historic Downtown, Dining, Shopping, and Arts
Victorian-era architecture lines Main Street, which anchors more than 550 shops and restaurants. The historic district includes well-preserved 19th-century mining-era buildings alongside contemporary galleries, boutiques, and breweries. Summer brings outdoor concerts, art festivals, and a farmers market. Winter brings après-ski culture that extends well past the lifts closing – Breckenridge has the strongest nightlife offering of any Summit County town.
Keystone Colorado Activities for Families and Outdoor Lovers
Keystone Colorado activities skew family-friendly across both seasons. In winter, the resort offers night skiing – one of the few in Colorado – alongside terrain for beginner through expert. Warren Station at River Run Village hosts live music events year-round, including the Winter Bluegrass Weekend each January. Summer opens Keystone Stables for guided horseback rides through Soda Creek Valley, and the resort runs chairlift rides and bike park access through the warmer months. Keystone has special summer lift deals that make it one of the more accessible mountain experiences in the county for families on a budget.
Frisco Colorado Attractions Around Dillon Reservoir
Frisco Colorado attractions center on the water. Dillon Reservoir – one of the largest alpine lakes in Colorado – sits at Frisco’s edge, offering sailing, kayaking, paddleboarding, and fishing from the Marina Park and Peninsula Recreation Area. The Peninsula Recreation Area also hosts Frisco Adventure Park with Frisco’s 18-hole Peak One Disc Golf Course (free to play), ski and snowboard hill, snow tubing hill, horse drawn sleigh and chuck wagon rides, terrain park/railpark, Frisco Nordic Center, and miles of hiking and biking trails. The Frisco Historic Park and Museum covers the town’s mining and railroad history with a collection of original structures. Friday mornings from June through September, the Frisco Farmers Market runs at the marina from 9am to 2pm. The paved recreational trail from Frisco to Vail Pass is one of the county’s most popular bike routes – 22 miles of car-free riding with continuous mountain views.
Silverthorne Colorado Activities: Trails, Shopping, and the Blue River
Silverthorne Colorado activities attract a different kind of visitor than the resort towns. The Blue River running through town holds Gold Medal fishing designation – some of the most productive fly fishing water in Colorado, accessible directly from town. The Blue River Parkway trail follows the river through Silverthorne, connecting to a broader trail network that links to Dillon and Frisco. The Outlets at Silverthorne draw shoppers from across the county and from Denver – over 70 brand-name stores at mountain-town prices. In summer, the town hosts outdoor yoga, paddleboard rentals on the reservoir, and a farmers market at the Dillon Amphitheater on Friday evenings with free concerts.

Summit County CO Activities in Winter
Summit County activities in winter extend well beyond the four ski resorts. Snowmobiling tours operate out of Frisco and Breckenridge, covering backcountry terrain that skiers never reach. Snowshoeing trails are accessible from every town – many are free and groomed. Ice skating rinks operate in Breckenridge and Keystone’s River Run Village throughout the season. Dog sledding tours run from operators near Frisco and Copper Mountain. For the more adventurous, ice climbing routes form on frozen waterfalls in the Ouray-accessible corridors and on local formations near Breckenridge.
Copper Mountain opens its season in early October – typically the first major resort in Summit County – and offers a free chairlift ride with a nominal village purchase throughout the winter. The Friday Afternoon Club at Copper runs outdoor movies and live events through the season, making it a social destination beyond just skiing.
Fun Things to Do in Summit County CO in Summer
Fun things to do in Summit County in summer rival winter in variety. Lake Dillon Amphitheater hosts free Friday evening concerts through the summer – one of the county’s best no-cost traditions. The Dillon Farmers Market runs Friday mornings. Copper Mountain’s Friday Afternoon Club continues into summer with free outdoor movies and concerts.
Hiking and mountain biking trails open across all four resort mountains, with lift-accessed terrain at Keystone and Copper Mountain. Fly fishing on the Blue River and Ten Mile Creek draws anglers from across the state. Horseback rides at Keystone Stables and Rusty Spurr Ranch near Kremmling offer guided mountain experiences for all ages. Paddleboarding and sailing on Dillon Reservoir round out a summer activity list that keeps the county fully occupied from May through September.
