This was our first time staying at Bear Creek Lake. The park is not part of the Colorado Wilds or CPW State Park system, but daily vehicle fees are included with your camping reservation. Our towed vehicle was included when we checked in at the ranger station.
The campground is at the back of the park, roughly 2 miles from the entrance. There is a lot of bike traffic and windy roads. Sites are mostly level, electric only, and relatively close together. We stayed in Site 41 which was walking distance to the pit toilets and water spigot. We had no trouble fitting our 29' Class C, tow dolly, and towed vehicle.
We filled our 7 gallon water jugs at the spigot to top off our fresh water tank. The spigot is the terrible skinny faucet that is not threaded as to dissuade RVers from connecting a fill hose to it. If you want to fill water jugs like we did, bring a short (<6') hose and a water bandit so that you don't waste water.
Pit toilets and flush bathrooms were clean and well maintained. The bath house at the center of the campground features coin operated hot showers, $2 for 10 minutes. The water temperature was very hot, but manageable. A great convenience since there are no sewer hookups at the sites.
This is a great place to camp if you want to explore Morrison, Golden, or catch a show at Red Rocks. The main park entrance closes at 9:30 and a back gate accessible from I-470 opens that allows access to the campground. We had no trouble getting an Uber to pick us up to go to Red Rocks, but had several driver cancellations trying to get back after a concert.
