Little Maud Campground is a pretty campground next to Ruedi Reservoir, which is quite large and open to both motorized and non-motorized boating. This campground, while still very accessible, is a bit off the beaten path (14 miles east of Basalt, CO) and therefore nice and quiet.

4 stars out of 5 because the campground is pretty open (not many trees), so there isn't much privacy.
