New Hampshire's tallest single-drop waterfall, estimated between 140 and 200 feet, reached by a popular Crawford Notch trail.
Arethusa Falls is widely called New Hampshire's tallest single-drop waterfall, though the exact height is genuinely disputed: an 1875 survey put it at 176 feet, the Appalachian Mountain Club has estimated closer to 140 feet, and newer LiDAR-based analysis suggests roughly 155 feet. Whatever the precise number, it's a serious drop by Northeastern standards, fed by the headwaters of Bemis Brook over a granite cliff on Crawford Notch's western slope.
The Arethusa Falls Trail climbs about 800 feet over roughly 1.5 miles from US Route 302, a steady but generally moderate grade that most guides rate accessible to families and beginner hikers willing to handle the elevation gain. A self-serve $5 parking fee applies at the trailhead lot in Crawford Notch State Park; conditions can be icy in colder months, so check seasonal advisories first.
