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, check the booking system directly for cancellations, or book a cabin or vacation rental nearby.
Warm water, thinner crowds after Labor Day, and great fishing — an easier, pleasant month. (Watch tropical weather.)
