Backcountry vehicle passes for the upcoming summer season are now available on Recreation.gov (https://www.recreation.gov/timed-entry/10089849). Starting today, reservations can be made for May 15 through May 31.
Future batches will be released on the first of each month. For a detailed list of release dates, visit the park’s Backcountry Experience web page. Any passes that have not been reserved will still be available for day-of reservations. In addition, all visitors on foot, bike, or horse can continue into the backcountry.
Exceptional Valles Caldera National Preserve experiences do not require a backcountry vehicle pass. Visit Valles Caldera’s Front-country Experience web page to learn more about the wonderful hikes, historic settings, volcanic and scenic vistas, old- growth ponderosa pine forests, and ranger programs available.
