Eldo Shuttle

Climber at Eldorado State Park, Eldorado Springs, Colorado.

The Eldo Shuttle 2022 season is over. The Shuttle will resume service in late May 2023.

Boulder County, Colorado Parks & Wildlife, and the City of Boulder offer a FREE shuttle bus service on weekends and holidays during the summer and fall to carry passengers from US 36 & McCaslin or Boulder to Eldorado Canyon State Park and the Marshall Mesa, Doudy Draw, and South Mesa trailheads, which are popular hiking, sightseeing, climbing, and biking destinations south of Boulder. The shuttle, operated by Via Mobility Services, helps address increased parking and traffic congestion-related impacts in Eldorado Springs, within the state park which connects to Walker Ranch, and along CO 170.
