In 2012, Six Flags combined Great Adventure Park with the Wild Safari Area to form a single 475-acre theme park. As of 2018, the park contained 12 roller coasters. Three are world-class rides: El Toro, Kingda Ka and Nitro. Kingda Ka, with a top speed of 128 mph feels like taking off from an aircraft carrier. At 458 feet tall guests say on a clear day you can see both the Philadelphia and New York City skylines. Nitro, another fast roller coaster, offers a panoramic view of the New Jersey countryside. El Toro is one of the tallest wooden roller coasters at 181 feet. The park includes a Safari Off-Road Adventure that has over 1,200 animals. It is the largest drive-through safari park in North America.
