Admission to Big Bend National Park is $30 for one private, non-commercial vehicle. The pass is valid for seven days. While in Big Bend National Park, make the drive from Mule Ears Viewpoint to the Castolon Visitor Center for the greatest bloom viewing. Take a drive along River Road for some more spectacular bluebonnet views. Even without the bluebonnets, Big Bend National Park is one of the most scenic areas of Texas. The incredible bloom this year is the icing on the cake.
