Sunnyside Campground
October 2026
About
Overview
Sunnyside Campground is located along the southeast side of Cougar Reservoir at 1,700 feet in elevation. A large grove of conifers provides shade to these campsites. Motorhomes and trailers not recommended due to the steep entrance into the campground.
Recreation
Hiking in the area is outstanding in nearby Three Sisters Wilderness, along Rebel Creek. Hikers will enjoy exploring other trails including the French Pete Trail, Box Canyon Trail, Indian Ridge Lookout, and several day hikes within the Cougar Recreation Area. After a fun day on the lake, relax and enjoy Terwilliger Hot Springs, a day use area along Rider Creek.
Facilities
The campground offers vault toilets and garbage collection. Individual campsites include a fire ring and picnic table. Easy access to the lake is possible from this scenic location. There is no water available, campers will need to bring enough for the duration of their stay.
Natural Features
Situated near the South fork of the McKenzie River on the Willamette National Forest, Cougar Reservoir is part of the Cougar Recreation Area. Wildflower and wildlife viewing are abundant.

Is SUNNYSIDE CAMPGROUND fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
CampHawk watches SUNNYSIDE CAMPGROUND in Blue River, OR for you. We recheck it every 15 seconds, around the clock, and the moment a site opens we send a text, an email and a push notification — and on Recreation.gov we can put the site straight into your cart, so it is held while you get to your phone.
Searching is free and needs no account — the calendar above is live right now. Watching SUNNYSIDE CAMPGROUND for cancellations is the paid part.
