Eldo Shuttle GraphicFree Summer Weekend
Hiker Shuttle

May 28-Sept. 5, 2022

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, and when it’s full, cars are turned away. Instead, take the free* summer weekend shuttle from Boulder to the 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.

Now More South Boulder Trails, Too! In addition to Eldo State Park, the shuttle now services three city trailheads in South Boulder: Marshall MesaDoudy Draw and South Mesa trailheads.

*Park fee required for visiting Eldorado Canyon State Park.

Additional Tips
  • Don't Chance It, Ride the Shuttle Parking is extremely limited inside Eldo, and there is no parking available outside the park. When parking is full, you won’t be allowed in. Don’t chance it. Park at one of the lots and ride the shuttle instead.   
  • Bikes, Dogs and Gear Welcome Plus each bus has a bike rack that holds up to 3 bikes. 
  • McCaslin Park-N-Ride Tips To minimize transfer wait time, catch the McCaslin bus at the top of the hour (8:00, etc.). On your return from the park, the optimal time to catch the park bus is at the half hour (2:30, etc.)
