Johnstown Flood National Memorial

In 1889, the South Fork dam broke, releasing 20 million tons of water onto surrounding communities. This is a key spot to learn about one of Pennsylvania's greatest disasters.

The visitor center overlooks the flood site, which resulted in around 2,200 deaths. It may be grim, but the museum at the Lake View Visitor Center tells an important story. Displays, old photographs, and a short film bring visitors back to that tragic day. You're sure to feel small beneath a full-sized replica of the 40-foot flood wave.

Head outside to embark on the ranger-guided Path of the Flood Hike. You have two choices—a rugged 8-mile segment and a 5-mile segment through urban areas. If your feet need a rest, opt for a "Path of the Flood" van tour guided by a park ranger. Keep in mind this tour is only available in the summer.

You can also walk through the South Fork Fishing and Hunting Clubhouse. The club owned the South Fork Dam when it failed, and the original 47-room building still stands. At the end of the afternoon, explore the surrounding grounds and hiking trails. The 165-acre park is the perfect place to take in the natural beauty of Pennsylvania.

The memorial is open year-round, so stop by to pay your respects. This site may be somber, but it tells a crucial piece of America's rich history.
