Booking Bentsen-Rio Grande Valley State Park in September
Texas state parks open reservations exactly 5 months in advance at 8 a.m. Central — so for a September trip, the booking window opens in April. Popular weekends can disappear within minutes of the window opening. If your dates are already full, set a Camp.land alert and we’ll email you the moment a cancellation opens.
