Checkpoints operated by U.S. Customs and Border Protection are located on all north/south highways leading to and from the Big Bend area. These checkpoints are staffed 24 hours a day, 7 days a week.

Each vehicle traveling north is met at the checkpoint by a Border Patrol agent for a quick visual inspection and brief questions to determine citizenship. The process is routine, and most stops average less than a minute in duration.

Foreign nationals planning to visit the Big Bend region should be sure to carry the appropriate documentation to avoid unnecessary delays, as Border Patrol agents are required to determine the immigration status of every traveler.
