Harriman State Park
The second largest state park in New York with over 200 miles of trails, 31 lakes and reservoirs, and two swimming beaches. The park is massive and offers everything from easy lakeside strolls to challenging mountain hikes. Lake Sebago and Lake Welch have lifeguard-staffed beaches perfect for families. The trails range from flat lakeshore walks to rocky ridgeline scrambles with Hudson Valley views. It is an incredible outdoor playground close to New York City and a great place to introduce kids to serious hiking.
