Arethusa Falls is claimed to be New Hampshire’s tallest waterfall as all 160' of its falls are in one continuous drop! Located on US-302 access to the falls can be made by hiking the 1.5 mile moderately difficult trail. The falls were first discovered by Edward Tuckerman in 1875 and he chose the name “Arethusa” which in Greek mythology, was the name of a nymph that turned into a fountain.

Crawford Notch State Park has 5,775 acres providing access to numerous hiking trails, waterfalls, fishing, wildlife viewing, and spectacular mountain views. Crawford Notch State Park is rich in history with the famous Willey House. The campground in the park is Dry River Campground and offers 36 wooded sites.

This park is always open for recreation unless closed or restricted by posting. During off-hours and the off-season, the park is typically not staffed, comfort stations are not available and gates may be closed. The off-season poses unique risks inherent when participating in outdoor recreational activities. Please be aware that many State Park areas and trails are not staffed during the off-season, and day-use fees are not collected. Recreationists should possess the necessary knowledge, skills, and equipment to ensure their safety. Users assume all risks while recreating in State Park lands.

Willey House Operating Schedule: The Willey House is open full-time only beginning in May and closes in October. Operating hours are Monday through Friday 9 am Saturday and Sunday from 8:30 am to sunset.

Arethusa Falls, nearly 200 feet high, are the highest falls in the state and certainly worth a visit. The access road to the 1.4-mile trail leads off US-302, 0.5 miles south of Dry River Campground. The first 0.6 miles is fairly rocky and moderately steep, while the latter half of the trail ascends through open hardwoods via a new relocation of the trail. Return via the same route or complete a 4-mile loop past Frankenstein Cliff to the start point.
