Pre-historic Indians settled here thousands of years ago. Still the park remains wild. The National Park Service has worked diligently to bring this unique park back to its natural state so that visitors can continue to enjoy its primitive beauty for many years to come. The best time to visit Big Bend National Park depends greatly on what part of the park one intends to frequent, how much solitude one desires, and one's comfort level in varying temperature ranges. During the summer the desert temperatures can be brutal, and most visitors keep to the Chisos Mountains.
Winter nights are quite cool, sometimes reaching below freezing, but the days can warm up nicely.
My rule of thumb for what to wear during any season is to prepare for extremes in both directions. For a year round weather chart provided by the NPS click here . Accommodations in the park range from motel lodging to campgrounds to backcountry roadside campsites. There is a full service restaurant and motel lodging in the Chisos Mountains Basin area. Horseback riding , river rafting, guided tours, nature programs, bird watching, wildlife viewing, and a visit across the Rio Grande to one of the Mexican border villages are just a few of the activities one can experience in this beautiful area.
