Peaceful Valley Scout Ranch is one of two Scout Ranches for the Denver Area Council. Located south-east of Denver only a short 90-minute drive, PV has three separate camps within the Ranch: Camp Deitler, Camp Chris Dobbins, and Magness Camp for Cub Scouts.
Bear Creek Lake Park has multiple camp sites, with a wide variety of amenities, including RV spots, and a large group campsite. Reservations are required in advance (WAY in advance) and need to be booked on the Lakewood, CO Parks Department website. Once you go to their site (at this point) it will not show any availability after the initial reservation. If you mess up and want to make changes, you will need to go directly to the old-school phone call.
