A Gift to Our Nation

In 1923, President Calvin Coolidge presented a gift to the people of the United States. He established the Allegheny National Forest in northwestern Pennsylvania with the mission of protecting the watershed of the Allegheny River while providing public lands for all to enjoy. One hundred years ago these lands needed care and protection. The land had been ravaged by wildfires and clearcutting.

Now in 2023, after 100 years of being a National Forest, the Allegheny National Forest is a 514,029-acre healthy hardwood forest, home to abundant wildlife, songbirds, wildflowers, American Bald Eagles, and osprey. In the northern section of the Forest, the Allegheny Reservoir offers boating, canoeing, and kayaking. Outdoor recreation sites include 14 campgrounds, cabins, and an extensive, four-season trail system for hiking, biking, mountain biking, ATV and snowmobiling in season.

To recognize and celebrate this 100-year milestone, multiple events are scheduled including the Centennial 100-mile Hiking Challenge, the ANF Centennial Geocache Trail, and the “100-year birthday” party for the ANF on September 24, at historic Twin Lakes.

Fall in the Forest and Nearby Kinzua Bridge State Park

During the fall, the tree-covered hillsides will change from green to a beautiful patchwork of color, sparkling yellow, brilliant orange and ruby red. Two premier sites for “leaf peeping” are the Kinzua Bridge State Park and the Allegheny National Forest.

Located within the Kinzua Bridge State Park is the Kinzua Sky Walk, “one of the top 10 most scenic skywalks in the world,” according to The Culture Trip, U.K. The skywalk extends 624 feet into the Kinzua Gorge, at a height of 225 feet, and it features a partial glass floor at the end of the skywalk. The Kinzua Bridge Visitors Center has a series of interpretive displays explaining the history of the skywalk which is the reinvention of six of the historic towers of the Kinzua Viaduct left standing after the tornado of 2003.

There are three trails at the park, picnic tables, a food truck, and a train themed children’s playground. The park is open from 8 am to 6 pm daily until the winter season. Admission and parking are free. Fall color usually peaks in the first two weeks of October. The park is located at 296 Viaduct Road, Mt. Jewett, PA.

Bigger is better, and during the fall, the sheer size of the Allegheny National Forest makes it a premier destination for fall leaf peeping. Add the diversity of the species of trees, and you have an unbelievable world of fall color.

A hiking trail in the Allegheny National Forest

In the ANF, the Longhouse National Scenic Byway, a 27-mile loop, offers three developed overlooks: Rimrock, Kinzua Point, and Jakes Rocks. Rimrock also features a picnic area and a trail through massive rock formations to the edge of the Allegheny Reservoir. Jakes Rocks offers a world class mountain biking trail near the developed overlook.
