Adventureland Resort, located in Altoona, IA, opened in 1974, marking this year as its 50th anniversary celebration. The theme park's design has several nods to Disneyland, such as the entrance area train station with two tunnels and a full Main Street thoroughfare. Adventureland is home to seven roller coasters and a total of fifty attractions, water park included. Over the last decade, the park has seen a high level of investment in new attractions, including The Monster, Dragon Slayer, Flying Viking and a major refurbishment of The Underground roller coaster.
