Just two miles into Colorado off I-70 there are several great options for free camping at McInnis Canyon National Conservation Area. And there's plenty to see and do in the area to make this a worthwhile stop. As far as camping goes, choose from a spot in one of the nice BLM campgrounds or choose one of the designated dispersed camp spots. And if you're set up for more adventure and rough roads, there are also camping options on the Colorado River.
