Campground was all we needed for a quick 1 night stopover at Twin Lakes.  There was no running water or dump station while we were there unfortunately.  Walkable from campsites down to lake (valley loop is a bit further).  Close to Mt Elbert trailhead.  Not much in town of twin lakes other than general store.  Good day use area at twin lake to rent paddeboards/kayaks, but water was very cold even in august.
