From November to April, the park requires reservations to enter after 5 p.m. No permit is required if visited between sunrise and 5 p.m. Permits are sold in advance only, through an online reservation system. Permits can be purchased up to 60 days in advance and can be purchased at https://texasstateparks.reserveamerica.com/tourList.do?contractCode=TX&parkId=1200067&fbclid=IwAR2gzfNrKCbnEDTUgS0zBzLwavtOLOpub66WPo8nZ3TCN_HJ5rX-FhMxF5w
