Rivers of Steel offers experiences that showcase southwestern Pennsylvania’s industrial and cultural heritage at their historical and 21st-century attractions in the Monongahela River valley and on the Explorer riverboat. Connect with Pittsburgh’s steel industry heritage on a guided tour of the iconic Carrie Blast Furnaces National Historic Landmark in Rankin and Swissvale, once part of the legendary U.S. Steel Homestead Works. Stop along the Great Allegheny Passage in Munhall and you’ll find yourself at the historic Pump House, site of the 1892 Battle of Homestead, which offers travelers a chance to walk a labyrinth, view public art, learn about the history of the site, or simply picnic by the river. Nearby in Homestead is the Bost Building National Historic Landmark, which serves as the Visitors’ Center for the Rivers of Steel National Heritage Area and offers exhibits on the region’s industrial and cultural heritage. Visitors arriving in Downtown Pittsburgh will want to follow the Three Rivers Heritage Trail to the North Shore for a sightseeing excursion on the world’s first green passenger riverboat, the Explorer, which docks at the headwaters of the Ohio River. All boat tour proceeds benefit environmental science education programs on the vessel. Get tickets and information at www.riversofsteel.com.
