It passes south about 35 miles and falls into the Connecticut at Barnet, about a mile below the foot of Fifteen Mile Falls, Vermont. Recreation in the out-of-doors is equally varied in the summer season. State parks and privately operated campgrounds provide everything from wilderness tent sites to complete hook-ups for RVs. Streams, ponds and lakes invite bass and trout fishing, canoeing, kayaking, sailing and boating. Winding blacktop roads are ideal for touring by car, motorcycle, or bicycle. Mountain resorts offer chair-lift assist to hiking and mountain bike trails, or extensive facilities for tennis, golf and swimming.
