Eldo Shuttle

Free Seasonal Weekend
Hiker Shuttle

May 24-Sept. 14, 2025
Weekends and Holidays

Eldorado Canyon State Park (or "Eldo" to locals) is a hiking, fishing, picnicking and rock climbing heaven, just minutes from Boulder. However, parking is limited, so timed-entry reservations are required on summer weekends and holidays. Instead, take the free* summer weekend shuttle from Boulder to the park.

By riding the Eldo Shuttle into Eldorado Canyon State Park, you get to bypass the weekend reservation system and have guaranteed entrance to the park that day. All guests, including those arriving by shuttle, are required to pay a fee or hold a valid pass to enter the state park.

Pick up the shuttle from the University of Colorado Regent Lot 306/308 (at Broadway and Regent), or six other stops, and ride in comfort to the state park. The shuttle and shuttle parking are free; there is a fee to enter the state park.

Shuttle to South Boulder Trails and the Eldo Pool, Too! In addition to Eldo State Park, the shuttle services three city trailheads in South Boulder (Marshall Mesa, Doudy Draw and South Mesa trailheads) and the Eldorado Springs Swimming Pool. Doudy Draw and the Eldo Pool are drop-off stops only. 

*Paid park pass required for visiting Eldorado Canyon State Park.
