Eleven Mile State Park

Eleven Mile State Park is a nature preserve centered around Eleven Mile Canyon Reservoir, featuring rocky shores and views of mountain ridges rising above the water. The reservoir is set within a canyon landscape that creates dramatic overlooks and secluded coves.

The dam controlling this reservoir was built in the 1930s as part of a major water project to supply Denver with drinking water. Its construction transformed the valley floor and permanently altered how water moved through the region.

The area has been home to hunting and gathering communities for thousands of years, with evidence of different indigenous peoples who lived across these lands. The landscape itself carries the memory of these earlier inhabitants through archaeological remains.

The park has campgrounds and boat launches spread around the shoreline at different locations. Several trails allow visitors to walk various lengths, though arriving early is wise since popular spots fill up quickly on weekends.

Beneath the reservoir waters lie the remains of 19th-century ranches and settlements that were flooded when the dam was built. Several campgrounds today carry the names of former landowners, preserving a connection to the submerged past.
