At the end of 11 Mile Canyon Road, where the South Platte River runs below the spillway of Eleven Mile Reservoir, Spillway Campground sits as the furthest point in along this stretch of campgrounds around Pike National Forest. The canyon walls rise sharply on either side, and rock formations are visible from many of the sites. Getting here requires navigating a washboard road that multiple campers describe as rough enough to rattle vehicles, and rock archways cut into the canyon walls narrow the passage in ways that limit what can make it through.
Sites vary considerably in character. Some sit right against the canyon rock, others are tucked up away from the main road with more separation from neighbors. Reviewers consistently single out sites closer to the entrance as more crowded, while those further in tend to feel more removed. Anna describes site 5 as "one of the most unique spots," set directly against the rocks. Site 12 has been noted for its space and natural boundaries, and site 16 works for small travel trailers. The campground hosts receive consistent praise across multiple seasons for keeping facilities clean and staying accessible to campers with questions.
Fly fishing draws a significant share of visitors here. The river runs through the campground, and Stephen K. notes it is "catch and release, flies only," which shapes the experience on the water. Day visitors also access the river, so the fishing corridor can get busy, particularly on summer weekends. A short overlook trail at the east end of the campground climbs steeply to views of the reservoir above, though trail markers are sparse in places.
Reservations are strongly recommended from late May through early October, the full operating window. The campground fills quickly on holiday weekends. RVs up to 40 feet are technically accommodated, but the rough access road and some narrow site layouts make the campground better suited to tents and smaller rigs. No hookups are available. Water is provided via pump, though some campers bring their own as backup. Cell service is limited throughout the canyon.
Cove Campground sits just up the road for campers who want a similar canyon setting with potentially more availability, and Witcher's Cove Campground — Eleven Mile State Park provides access to the reservoir itself for those who want flatwater alongside their stay.
Description
Overview
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.
Recreation
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.
Facilities
Spillway Campground offers about 23 reservable campsites. Parking aprons are gravel and can fit a maximum trailer length of 25 feet. Amenities include vault toilets, picnic tables, hand pump for drinking water, and campfire rings.
Natural Features
The campground, at altitude 8,500 feet, is located at the edge of Eleven Mile Canyon, furthest from the canyon entrance. Some campsites are shaded by scattered spruce and ponderosa pine. Spillway is the closest campground to the Eleven Mile Reservoir, which spans 3,405 surface acres and 5 miles in length. Eleven Mile Canyon was cut by the South Platte River and is bordered by polished gray granite cliffs.
