Colorado is home to , and last year, 19.5 million people visited them to enjoy the great outdoors.
The parks offer a diverse range of experiences and, of course, not all are as trafficked as the most popular ones. , consistently the most-visited in Colorado, welcomed about 3 million people in 2025, according to data from Colorado Parks and Wildlife, provided to The Denver Post. In terms of popularity, itap rivaled only by and , which saw 2.4 million and 2 million recreators last year, respectively.
Those three parks are large enough to support robust crowds and, good thing, since they’re near heavily populated areas. But if you’d rather avoid crowds, there are plentiful state parks that offer some remote serenity — as long as you’re willing to travel from the metro area. The seven state parks in southwestern Colorado, for example, saw roughly 1.6 million visitors total in 2025, which is less than the number of people who came through just on the Front Range during the same time period.
We’d argue a long drive is a small price to pay for some solace in the wilderness. So pack the car and use this list of the 10 least-visited state parks in Colorado to plan your next adventure. We’ve also thrown in five bonus destinations close to Denver to satisfy those looking for a shorter trip.
Note: We’ve excluded two state-managed shooting ranges and one park that’s open exclusively to hunters, which are annually among the lowest in terms of visitation.
