Splash Lagoon Indoor Waterpark Resort is a Polynesian-themed large indoor waterpark located in Erie, Pennsylvania.
The park is approximately 80,000 square feet (7,400 m2). It features seven water slides, two hot tubs, one large activity pool, and a children's area. The tiki tree house is four stories high and offers many activities. It is located on sprawling Upper Peach Street with many restaurants and retailers nearby. Connected to a Holiday Inn, Residence Inn, and a Comfort Inn; with many other hotels within a few miles. Splash Lagoon features a 6,500-square-foot (600 m2) arcade and a large Laser Tag area. The water park opened in 2003 and has one addition. Scott Enterprises, a local franchising company, built Splash Lagoon. Water slides swerve in and out of the building, giving it a distinct look.
In 2008, Water Parks Resorts Today named Splash Lagoon as sixth largest water parks hotels in North America.  In 2004, Splash Lagoon prepared to expand the waterpark with two new slides. One to be called Python Plunge, a tube slide, and a body slide called Shark Attack. The slides opened in 2005 along with Boston's Restaurant and Sports Bar. On February 25, 2008, it was announced that Splash Lagoon would be adding a wave pool by spring 2009.[ citation needed] On September 17, 2011, after years in the planning, the 30,000 square foot wave pool opened to the public, making Splash Lagoon the third largest indoor water park in the country. The same year, Treetops Indoor Rope Course opened where people can climb 30 feet above the area near Shark Attack and Python Plunge.
