Crawford Notch State Park

"This pretty park maintains an extensive system of hiking trails. From the Willey House visitor center, you can walk the easy 0.5-mile Pond Loop Trail, the 1-mile Sam Willey Trail and the Ripley Falls Trail, a 1-mile round-trip hike from US 302 via the Ethan Pond Trail. The trailhead for Arethusa Falls, a 1.5-mile one-way hike, is 0.5 miles south of the Dry River Campground on US 302. Serious hikers can also tackle the much longer trek up Mt Washington."
