It’s actually kind of a surreal experience. I drove into Big Bend NP from the eastern side and made my way to some pretty nice views of the Rio Grande before coming back out through the western side of the park.
I first stopped at the Santa Elena Overlook and then made my way to the Santa Elena River Access. I was even able to enjoy a very light craft beer I bought in Castolon. Though the visitor center in Castolon is closed in the summer months, the store remains open year round.
