Eldorado Canyon State Park

Tucked into a dramatic setting south of Boulder, Eldorado Canyon State Park is the outdoor recreation mecca for anyone with a passion for rocks and nature.

Tucked into a dramatic setting south of Boulder, Eldorado Canyon State Park offers day-use recreation opportunities with a spectacular backdrop. Watch climbers scale towering cliffs, wander streamside trails with scenic vistas, and fish for trout in Boulder Creek.

The Fowler Trail snags views of the gorge from its entire length, and is a great trail for families on foot. The Rattlesnake Gulch Trail is more challenging, offering a 1.4-mile climb to the ruins of the Crags Hotel (which burned down in 1913).

Mountain biking and horseback riding are allowed on appropriate trails but note that horses must be on a leash at all times. Weekends and holidays can fill the park to capacity.

Rock Climbing

Climbers from across the country flock to Eldorado Canyon to test their mettle on its towering sandstone walls. The canyon offers classic climbs that include the infamous Bastille Crack, which starts right off the road. The park is home to wildlife such as mountain lions, black bears, and golden eagles. It’s essential to follow Leave No Trace principles, as the canyon is a natural habitat and some crags are closed to protect nesting birds.

Rock climbing is a dangerous activity and accidents can happen. Many routes at Eldorado Canyon pass over loose or suspect rock and the canyon’s location in a high-pressure weather zone can create a variety of hazardous conditions. A great place to also visit is Eben G. Park.
