We live in Colorado Springs but traditionally hit Mueller at least once a season while we had a pop up.  Not quite as good for our current RV - there are devil trees to maneuver around!  It is a beautiful wooded park with lots of trails.  Sites vary in size and type with a few pull throughs.   There are 3 very nice fully-equipped cabins also. If you're into geocaching, there are several that can be found in the park.  Beautiful place to get away and enjoy nature.
