Eldo Shuttle

Eldo Shuttle GraphicFree Summer Weekend
Hiker Shuttle

May 25-Sept. 2, 2024

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 (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, Too! In addition to Eldo State Park, the shuttle services three city trailheads in South Boulder: Marshall MesaDoudy Draw and South Mesa trailheads. There are no fees for visiting these trails.

*Park fee required for visiting Eldorado Canyon State Park.
