Eldo Shuttle

The Eldo Shuttle will begin running Saturday, May 24, 2025.

Free Shuttle Bus Service

Eldo Shuttle parked in front of a building with a rider and dog waiting to board and mountains in the background. Boulder County, Colorado Parks & Wildlife, and the City of Boulder are offering a FREE shuttle bus service on weekends and holidays during the summer and fall to carry passengers from US 36 & McCaslin and from 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.
