Spillway Campground is perched along the South Platte River near the base of the dam of Eleven Mile Reservoir. Adventurists and families alike will find things to do here. Birding is excellent, as is hiking. Rock climbers enjoy the solid rocky cliffs of the canyon and fly fishermen find abundant catches in the river.
Hike the Overlook Trail for breathtaking views of Eleven Mile Canyon and Reservoir. Occasionally, Golden Eagles can be viewed nesting in the nearby granite cliffs and crags. Springtime brings higher chances of spotting Bald Eagles.
Visitors enjoy fishing by shore or canoe. Rainbow and brown trout, kokanee salmon and pike are among the species anglers are likely to find.
