Introduction
Eleven Mile Canyon runs along South Platte River which is fed by Eleven Mile Reservoir. The road along the canyon use to be a railroad bed but is now a great scenic drive. There are many activities, but is a very popular fishing spot year round.
Eleven Mile is towards the west side of Pikes National Forest, which means there are only smaller foot hills. Because of the smaller foot hills it is very easily accessable and known for climbing and fishing.
Hiking
Overlook Trail
Easy
The overlook trail is located at the end of the canyon, where the canyon meets the reservoir. It is a quick trail 0.8 mile trail with great views. The trail is located right at the base of Spillway Campground and right down the road from idlewilde picnic area and cove campground.
The trail is a little steep but still pretty easy. Just make sure you take the large switch back (past walking inbetween the rock formation). If the trail is snow covered it can be a little difficult to see where the trail is and easy to get confused. Regardless of where you end up, there are great views.
Hardrock Trail
Easy
This trail is a short point to point trail. It goes from Riverside Campground to Blue Mountain Campground. The trail is lightly travelled and goes by Teller Pegmatite Mine.
Biking
Eleven Mile Canyon does not have many trails and the trails that are there are not very biking friendly. Fortunately, the forest service roads are well maintained and offer great views and tunnels.
Camping
The canyon has a large amount of camping sites. Just remember camping is only allowed in designated sites. Camping requires a reservation which (according to the forest service's website) can be made at recreation.gov

Fishing
Eleven Mile Canyon has become "a big deal" for fly fishing. This section of the South Platte River is fishable year round as it rarely freezes over in the winter. It is rated as intermediately difficult to fish, but regardless of what you catch it offers great views.
Before heading out, consult Fly Cast USA for weekly reports, river flow info, and recommended flies.
