Valles Caldera National Preserve

Valles Caldera's backcountry road system opens to vehicles on Friday, May 15, 2026. Forty vehicles passes will be issued per day through November 15, when the route closes for the 2026 season. Passes may be reserved up to 3 months in advance at Recreation.gov. Any remaining daily passes will be available on a first come, first served basis in the Volcano Discovery Center.

The VC09/South Valle Toledo/Posos Trail from the Valle Toledo parking area to the eastern park boundary is closed for restoration. The NPS is working on a trail reroute and will provide details as soon as possible.
