Voted Best in the Nation by USA Today readers, Letchworth State Park sprawls over 14,000 acres, containing innumerable vistas, more than 30 waterfalls, miles and miles of easy to strenuous hiking, horseback and biking trails, museums, whitewater rafting and kayaking along the Genesee River, and hot air ballooning. The park is also open for winter sports, including snow tubing, cross-country skiing, and snowmobiling.
The historic, restored Glen Iris Inn, located adjacent to Middle Falls, offers rich overnight accommodations. It also offers fine dining and is open for breakfast, lunch, and dinner. Another restaurant is located at Lower Falls.
Nearby is the William Pryor Letchworth Museum, which contains the collections of industrialist William Pryor Letchworth. The exhibits focus on the natural and cultural history of the Genesee Valley, and include archaeological artifacts of the Seneca nation, and displays on Mary Jemison, early pioneers, William Pryor Letchworth and the Genesee Valley Canal.
At the southern reaches of the state park is the Portage Viaduct, an iron railroad bridge that was completed in 1875. At 820 feet high, it is one of the highest railroad crossings in the United States. At the northern end of Letchworth is the Mount Morris Dam. Construction began in 1948 with the new dam opening in 1954. Designed to control flooding in Rochester downstream, the Mount Morris Dam is the largest flood control device of its kind east of the Mississippi.
