The preserve consists of 1,525 acres of class I wetlands, uplands and forest along Crooked Creek in both Jefferson and St. Lawrence counties. It is one of the most significant wetlands on the St. Lawrence River, providing habitat for countless species, and acting as both filter and buffer when water levels fluctuate. Bald eagles regularly fly overhead and the creek meanders for miles of quiet paddling. The Macsherry Trail consists of a short loop of about 1.5 miles and a long loop of nearly 3 miles. Passing beaver ponds and meandering through woods, it leads to the creek itself with a wonderful view of Chippewa Bay, before circling back to the trail head.
