Franconia Notch State Park
For a quintessential Franconia Notch experience, follow the Basin Cascade trail. It is a moderate 2.6 miles hike that starts with a beautiful natural 10-foot waterfall. You can either follow the trail into the woods or branch out to a place where you can walk out to the Pemigewasset river.
Wellington State Park
Wellington State Park has the largest freshwater swimming beach in New Hampshire, and one of the deepest/clearest lakes in the state, so there are plenty of water-related activities to do here (there’s a kayak rental shop). There are also hiking trails that loop around the lake, picnic areas, volleyball and horseshoe courts.
