Six Flags Great Adventure, Jackson, has announced a second major addition for the 2019 season with the introduction of Calypso Springs. This activity pool is Six Flags Hurricane Harbor’s largest new attraction since the water park opened in 2000. The key features of Calypso Springs include a 100,000-gallon beach entry-style pool, an obelisk-style fountain with spontaneously erupting geyser, an open lounge deck with hundreds of chairs for sunbathing, oversized umbrellas, Bimini shade covers available for rental and a new dining location. Calypso Springs is slated to open summer 2019.
