We drove down anout 3 miles to knowles overlook campground overlooking the Colorado River. There are about six sites and a pit toilet, its free. So beautiful and peaceful. Only noise is the sound of the river and the train going by occasionally. Views are gorgeous. Lots of bike trails nearby as well. You take exit 2 off i-70 (Rabbit Valley exit) , go left to the McInnis Canyon area, at the first fork go right, at the second fork past the parking lot take a left, its about 2.8 miles down through pastures, rock formations and bike trails. Well worth the drive! Do the drive during the day so you dont get lost.
