We stopped here on our way to yellowstone and of the 4000 miles we traveled, Sibley Lake caught our interest most. This area is so beautiful! Hard to beat camping in the Bighorn mountains. Made a lasting impression on my wife. Sites were on the smaller size, lacking gravel and could be bad after heavy rain or snow with mud. We saw moose cow and yearling while we walked to the lake. Camp host very accommodating. Camped here in 32' motorhome. We will return.
