A really nice CG on the Cache la Poudre river. Most campsites are just a few steps away from the river. Many sites are well separated from the others. All the back-in sites are large, most are fine for 40' rigs. All sites are level and have nice tent pads. There are several tent only sites, some right next to the river. The few pull thru sites are for 25' or smaller rigs. All the NF campgrounds along this 15 mile stretch of Cache la Poudre river have nice level gravel campsites. Kelly Flats CG does not take reservations. Really nice for those of us who can arrive on a Wednesday and plan on staying through the weekend, but don't know the area and which campsites are nice. In the peak summer period, these CG's fill up on weekends. So, if you know exactly which campground and which campsite you want to stay in, you can make reservations in four other CG's along the river. Note: This is a NF CG, no water, elect or sewer hookups. Just a nice pretty place to spend a few days. We camped here in a Motorhome.
