Current and Forecast Conditions
Be prepared! Always check the weather forecast, Medano Creek conditions and forecast flow, Medano Pass Primitive Road conditions, and any alerts before your visit. Plan ahead for conditions to expect each month of the year.
The Visitor Center is open every day of the year except Thanksgiving, Christmas, and New Year's Day.
Fall, Winter, Spring (Labor Day until Memorial Day Weekend): 9:00-4:30 daily
Piñon Flats Campground is open April through October each year (closed November through March). Car camping is not permitted in the national park or preserve during these winter months. A few area campgrounds are open throughout the year. The Medano Pass Primitive Road (high clearance 4WD) is open for driving and camping late spring through fall, as road conditions permit. Backpacking is available year round, but you must be prepared for snow and frigid nighttime temperatures in winter, and potential spring and summer storms that can bring high winds or lightning and rain. Check the weather forecast before you visit!
