Hey Seniors! Trade your cap and gown for coaster screams and dance floors when Six Flags Fiesta Texas hosts its all-night Grad Nite party on May 14. 🎢🎓
SAN ANTONIO — Caps? Ready. Gowns? Steamed. Roller-coaster scream? Fully loaded.
Six Flags Fiesta Texas is bringing back its annual Grad Nite celebration on Thursday, May 14, 2026, giving graduating seniors from across San Antonio, Central and South Texas a chance to celebrate in true Fiesta City fashion, with the entire park to themselves.
The private, after-hours event runs from 6 p.m. to midnight, once the gates close to the public. That means no long lines, no little kids cutting in front, and plenty of time to squeeze in just one more ride before midnight.
Grad Nite gives seniors exclusive access to the park’s biggest rides, plus dance parties, games and food, all wrapped into one high-energy night designed to be fun, safe and way more memorable than another hotel ballroom.
“Graduation marks an important milestone for Texas students and the park is honored to help celebrate their achievements,” said park manager Robert Bustle. “Grad Nite turns Fiesta Texas into an event where seniors can make lasting memories together in a safe, fun and unforgettable environment.”
The event is open only to graduating seniors and their chaperones. Students must stay inside the park for the duration of the night, with transportation provided by school buses or approved chaperones.
Schools are encouraged to reserve early because this party sells out faster than a front-row seat on Iron Rattler.
