Oswegatchie Hills, Niantic
Oswegatchie is located in Niantic CT and is a town owed park largely maintained by the local Boy Scout Troop.
There are a verity of trail features and little surprise natural jumps and such on the way out with it ending at a small mountain climb or go down to an old horse shoe shaped rock quarry with multiple 3-8 foot, stone steps to play on or ride through the maze of ramped sections down it.
The following description is from the Trailfoks page.
Rising dramatically above the Niantic River is a rugged forest filled with wetlands, streams and spectacular rock formations. This impressive landscape, created by glaciers 12,000 years ago, once felt the footsteps of Nehantic Indians.
Known simply as “the Hills” or “the preserve,” this sanctuary contains seven miles of trails enjoyed by thousands of hikers a year, and also serves as a natural outdoor laboratory for students studying botany, biology, geology and other sciences.
This is the 457-acre Oswegatchie Hills Nature Preserve, a critical element of the Niantic River watershed that provides habitat for scores of species of birds, mammals, reptiles, amphibians and insects. Several rocky ridgelines also support one of the few remaining concentrated stands of pitch pines and scrub oaks in Connecticut.
