Hidden deep in Chestnut Ridge Park, the Eternal Flame Falls are a natural phenomenon and make a memorable day hike for visitors. As one of a few hundred "eternal" flames worldwide, it is fed by a natural gas seep that breaks through the earth's surface. The park also has bicycle and hiking trails, picnic Areas, playgrounds, tennis courts, and a disk-golf course. In the winter, it is ideal for cross-country skiing, sledding, snowmobiling, and is even equipped with two towers and four chutes for tobogganing. The Eternal Flame hiking trail is a little challenging, but clearly marked and fun for the kids.
