DENVER, Colo. — You can make reservations at most campgrounds in Colorado’s national forests and national parks up to six months in advance through Recreation.gov. Be sure to select the “flexible” dates option so you can quickly look over a month of availability at once.
For some sites, you’ll have to pay close attention to that six-month mark. Established campgrounds near Maroon Bells — Silver Bell, Silver Bar, and Silver Queen — disappear as they become available. If you want to book July 10, the day to do that would be Jan. 10. (Shout out to the excellent Miss Adventure Pants for that suggestion.)
