Letchworth State Park is a large state park in western New York protecting a scenic 17-mile stretch of the Genesee River gorge and its waterfalls. The park is noted for high sandstone cliffs and three major waterfalls where the river drops through the gorge.

Visitors use a network of overlooks, hiking trails and picnic areas to view the river, the falls and the surrounding forest; the park also offers paddling, hot-air ballooning and seasonal programs. The historic Glen Iris estate overlooks the river and contains visitor services.

The core of the park originated from land donated by William Pryor Letchworth in the early 20th century to preserve the gorge and surrounding landscape. The park extends over several thousand acres of protected forest and river corridor in western New York.

  • Gorge length: Protects a roughly 17-mile section of the Genesee River gorge, often called the "Grand Canyon of the East" for its deep cliffs and waterfalls.
  • Cliffs and trails: Cliffs reach heights of several hundred feet and the park includes multiple overlooks and long hiking trails along the rim.

  • Upper, Middle and Lower Falls: A series of three major waterfalls on the Genesee River within the park, with rugged cliffs forming the gorge walls.
  • Glen Iris Inn and estate: Glen Iris Inn and historic estate area offering views across the gorge and services for visitors.
