Masks or facial coverings not required to ride

Masks or facial coverings are not required to ride the shuttle, but passengers who would feel more comfortable wearing a mask are welcome to do so.

Take the bus to the shuttle

Rather than driving to your trailhead or one of the shuttle parking lots, visitors are encouraged to take the RTD route SKIP, DASH, Flatiron Flyer or other bus routes that stops along Broadway in Boulder or at US 36 & McCaslin to connect to the Eldo Shuttle.

Parking is extremely limited inside Eldorado Canyon State Park and at the Doudy Draw and South Mesa trailheads. When parking inside the state park is full, you will be not be allowed in, and there is no public parking nearby. Don’t chance it - park at one of the shuttle lots and ride the shuttle instead! Illegal parking could result in fines and/or towed vehicles.

Timed entry reservations not required to ride the free shuttle

Colorado Parks & Wildlife recently approved a pilot timed entry reservation system for visitors driving to Eldorado Canyon State Park. This program will begin later this summer, and require visitors accessing the park via private vehicle to make a reservation for access between 5:30 a.m. and 5:30 p.m. Reservations are not required for shuttle parking, or to ride the shuttle.
