The park offers hiking, camping (including a hike-in, primitive area) and canoeing and kayaking on the Delaware River.

The forest is named after Charles Campbell Worthington, who, throughout the late 1800s, purchased 6,000 acres (24 km2) of land of both sides of the river, including parts of Mount Tammany.

Worthington gave Sunfish Pond the name of Buckwood Lake, and used it as a water supply for his lodge.

The Old Mine Road, one of the earliest roads in the area, runs along the Delaware; it was used for transporting copper and slate from nearby mines and quarries, and is believed to have originally been a Native American trail that saw use by fur traders and Dutch settlers.

The 258 acres (1.04 km2) Sunfish Pond Natural Area consists of a glacial lake and the surrounding chestnut oak forest, and can be reached by a steep and rocky climb along the Appalachian Trail.
