Today is opening day for the 2017 season at Six Flags Over Texas. The park will be open from 10:30am to 8:00pm. Please note that the park will also be open daily from March 9th through March 19th in honor of Spring Break. Check out our Park Hours page in regards to what times the park will be open. For the 2017 season the park will be adding The Joker, a brand new 4D free spin coaster. We expect the attraction to open in late Spring. Happy opening!
