Eleven Mile State Park
Location: Park County, west of Woodland Park near the town of Lake George

The large reservoir at Eleven Mile State Park is a premium spot for fishing. Rainbow, brown, cutthroat, kokanee and pike inhabit the waters of the park.

Canoeing, camping, hiking and biking, as well as sailing, windsurfing, kayaking, motor boating and winter ice boating, make Eleven Mile a year-round destination.

The park is also a prime location for birders and for duck hunting in the fall. Neighboring Spinney Mountain State Park also is popular for birding and fishing.

The Eleven Mile Canyon Reservoir is one of seven man-make lakes serving the city of Denver.
