Big Bend in December: what the park service says

December splits in two at Big Bend. The weeks before the holidays are part of the full-every-night stretch the park service describes for November through April, and then Christmas to New Year's is one of the park's busiest periods of the year. If your dates fall in that holiday window, have a second plan for the day: rangers meter cars into the Chisos Basin, Lost Mine Trail and Boquillas crossing lots once they fill, so an early start or a quieter corner of the park saves the most time.
