The gates never close
The park is open 24 hours daily, all year. The Panther Junction Visitor Center is open daily, 8:00 a.m. to 6:00 p.m., but may be closed on Christmas Day. The entrance stations and other visitor centers have variable seasons and hours.

When is it busy?
Big Bend is relatively uncrowded much of the year. Visitation is highest in March and April. The park is extremely crowded during spring break, which is usually the second and third week in March. Easter weekend, Thanksgiving weekend, and the week between Christmas and New Year's Day are also very busy. All lodging and campsites are usually full during these periods. Visitation is lowest in August and September.
