Adventureland opens for the season in early May and remains open until the end of Phantom Fall Fest in October. Adventure Bay water park operates from Memorial Day Weekend until Labor Day Weekend.
The best time to visit Adventureland really depends on what you’re looking for! Weekdays typically have lighter crowds, while weekends and special events bring extra energy and entertainment. Summer is perfect for enjoying both Adventureland and Adventure Bay, while fall brings seasonal favorites like Oktoberfest and Phantom Fall Fest. No matter when you visit, there’s always something fun happening!
