Big Bend National Park covers over 801,000 acres -- more land area than the State of Rhode Island -- and averages 350,000 or fewer visitors per year.
As of July 2009, Big Bend National Park is open 24 hours a day, 365 days a year. The Panther Junction visitor center is open from 8 a.m. to 6 p.m. every day except, sometimes, for Christmas Day.
