I always appreciated a good rec path and seek them out while traveling through the state or around New England. Rec paths appeal to everyone of every ability for a few reasons: they are often flat, exist in a super scenic area, and provide a safe place for any non-motorized activity. I've seen people walk, run, hike, bike, scooter, rollerblade, you name it when visiting the park.
I started upping my mileage to include some long runs and knew I was bringing Whitney. It had been a while since I visited Hammonasset State Park a few towns over in Madison, Connecticut. It's known for its paved rec path through the park, beach access, campground, and nature center. It's all in the details like the rentable pavilions here families host birthday parties, the playground along the path, water stations along the trail (attached dog water stations included), boardwalks, a nature center, and some trails through the park. It's a great family-friendly place.
