9. Pay Park Fee at Panther Junction Visitor Center. Speaking of the National Park Service, there's a fee to enter Big Bend National Park, which I recommend you pay to support the care and maintenance of the park. You can pay admission at the Panther Junction Visitor Center, the park's headquarters. Entrance Fees (valid for seven days)
If getting off the highway is more your style, this is definitely a National Park that you’ll have fun in. Outside of the park is the famed River Road. Highway 170 runs through Big Bend Ranch State Park, within feet of the Rio Grande River at times. This road is one of the best motorcycling roads in Texas.
