Wonder Lake State Park
New York’s Hidden 1,100-Acre Wilderness — 8.7 Miles of Trails, Highlands Trail Segment, 30-Acre Lake, Otters & Barred Owls, Mountain Laurel & Great Swamp Watershed in Putnam County
Wonder Lake State Park is a 1,100-acre state park spanning the towns of Patterson and Kent in Putnam County, New York. The park features 8.7 miles of hiking trails including a segment of the Highlands Trail, the 30-acre Wonder Lake, the 3-acre Laurel Pond, otters, barred owls, coyotes, and diverse wildlife, mountain laurel thickets, and protection of the Great Swamp watershed.
Wonder Lake State Park is one of the Hudson Valley’s best-kept wilderness secrets — a 1,100-acre expanse of rugged, mostly wooded terrain in Putnam County that sees far fewer visitors than its more famous neighbors. The park’s 8.7 miles of trails include a segment of the Highlands Trail, a long-distance route traversing the New York-New Jersey Highlands. The Wonder Lake Loop encircles the scenic 30-acre Wonder Lake at the park’s center, while the smaller 3-acre Laurel Pond provides a quieter destination. Wildlife is abundant — river otters, barred owls, coyotes, and wild turkey are regularly observed. The park protects a critical section of the Great Swamp watershed, making it ecologically significant beyond its recreational value.
