Head into the northern side of the Bighorns and you come across Sibley Lake. The campground has electric and non-electric loops. Sites are large and you find yourself under tall trees. The camp host keeps the vault toilets and campground clean. Drive through the campground, or take the road that skirts it to the left, and you find picnic areas. Launch your boat to catch some fish or just enjoy the day. We saw families having picnic celebrations on this holiday weekend. There is also a hiking/skiing route that has several loops. Go around Sibley or extend your adventure further. There is a donation box for trail upkeep. 

This is a nice campground that is closest to the towns in the east.
