What needs booking

Monitor Medano Creek Forecasts and Pinon Flats Availability

A standard park entry does not require a timed reservation, but the Pinon Flats Campground requires booking through official federal systems. Peak weekends during spring creek flow see extreme demand for local lodging. Always verify current entry policies and backcountry permit needs on the official NPS site before travel.
