The Lehigh Valley is one of eastern Pennsylvania's most populous regions, home to the lovely cities of Allentown, Bethlehem, and Easton. The valley, which is part of the larger New York City and Philadelphia metropolitan regions, is home to a plethora of cultural attractions, including the Allentown Art Museum, which showcases more than 11,000 works of art, and the ArtsQuest nonprofit organization, which presents cultural performances at Bethlehem's SteelStacks campus. Each year, Bethlehem hosts the annual Musikfest music festival over 10 days in August, attracting more than one million visitors. During the summer months, Dorney Park and Wildwater Kingdom offers high thrill amusement attractions, including the legendary Steel Force roller coaster, the first roller coaster to break the 200-foot height mark on the American East Coast. Other attractions include the Bear Creek Ski and Recreation Area, and the Wind Creek Bethlehem casino and resort complex.
