Do you have a link to the Colorado 1/2-price camping pass? All I can find is the entrance pass. Thanks.In Colorado you must make reservations for the state parks (no walk-ins) and they are often full within the first few minutes they are available (max 6 months ahead for reservations). But Colorado, too, has an annual pass that gives half price camping fees plus takes care of the daily charge for park entry required without the pass.
