Overview
Arethusa Falls is the tallest waterfall in New Hampshire, dropping over 140 feet down a granite cliff face in Crawford Notch State Park. The hike to reach it is only 2.8 miles round trip with about 800 feet of elevation gain, making it one of the most rewarding short hikes in the White Mountains. You get a genuinely impressive waterfall without a genuinely punishing climb. Crawford Notch is also home to the Crawford Path, the oldest continuously maintained hiking trail in the United States, and the Zealand Falls trail a short drive to the west, both worth considering for a fuller day in the area.
The trail follows Bemis Brook through mixed hardwood and spruce-fir forest, crossing the brook twice before arriving at the base of the falls. It's well-suited for families with children, casual hikers, and anyone looking for a shorter outing in the Whites that still delivers a memorable payoff. Dogs are welcome on leash.
The falls are fed by Bemis Brook, and their volume varies dramatically with the seasons. In late spring, when snowmelt swells the flow, Arethusa Falls is a thundering curtain of water. By late summer, the flow slows to a thinner cascade, still beautiful but a different experience entirely. If you want the full show, visit in May or early June.
The Route
Trailhead to Arethusa Falls (1.4 miles, 800 ft gain)
The trail starts from a parking area on the south side of Route 302 in Crawford Notch, about 5 miles south of the Willey House historic site. A sign marks the trailhead. The first 0.3 miles follows an old railroad grade (flat and wide) before the actual trail branches off to the right and begins climbing.
From this junction, the trail follows Bemis Brook upstream through a pleasant mixed forest of birch, beech, maple, and spruce. The grade is moderate and consistent, with no steep pitches that would trouble younger hikers. The trail surface is packed dirt with rocks and roots, typical of White Mountain trails. Footing is generally good but can be slippery when wet.
You'll cross Bemis Brook twice on the way up. The crossings don't have bridges, but they're easy rock-hops in normal conditions. In spring or after heavy rain, the water level rises and the crossings require more care. Waterproof boots or trail shoes with good traction are recommended during wet periods.
Along the way, two smaller waterfalls are worth a quick stop. Coliseum Falls is a short spur off the main trail at about 0.5 miles, a modest but pretty cascade in a narrow rock channel. Bemis Brook Falls is visible from the trail at about 0.8 miles. Neither is as impressive as the main event, but they set the stage.
At 1.4 miles, the trail reaches the base of Arethusa Falls. The brook drops over a sheer granite cliff in a single long plunge, fanning out over the rock face before collecting in a pool at the bottom. The viewing area at the base offers a direct look up at the falls. In spring, the mist from the falls reaches the viewing area, and the sound of the water drowns out conversation.
At the Falls
There's no developed viewing platform, just a rocky area at the base where you can sit, eat lunch, and take in the falls. The rocks can be slippery, especially near the pool. Keep children close and watch your footing.
Scrambling up the rocks to the sides of the falls is possible but not recommended. The granite is often wet and moss-covered, creating genuine slip-and-fall hazards. Several people have been injured here trying to get closer or higher for a better photo. The view from the base is the intended vantage point, and it's plenty good.
The pool at the base is shallow and cold. Wading is possible in summer, but the water temperature (barely above 50 degrees even in August) discourages extended swimming.
Extending the Hike: Frankenstein Cliff
If you want more after seeing the falls, a connecting trail leads from Arethusa Falls to Frankenstein Cliff, a rocky overlook with commanding views of Crawford Notch and the surrounding mountains. The loop adds roughly 3 miles to your total distance and about 500 feet of additional elevation gain, making the full Arethusa-Frankenstein loop approximately 4.8 miles.
The Frankenstein Cliff trail follows the rim of the notch through open forest with several viewpoints along the way. The cliff itself overlooks the old Maine Central Railroad trestle (the Frankenstein Trestle, named for an early landowner, not the novel). On a clear day, the views up and down Crawford Notch are excellent. The trail descends to Route 302 along the railroad grade, and you'll need to walk about 0.5 miles along the road back to the Arethusa Falls trailhead.
This extension is a solid moderate hike and a good choice if the falls alone feel too short.
What to Expect
Trail conditions: The trail is well-maintained and straightforward. There are no technical sections, no exposure, and no above-treeline terrain. The brook crossings are the only potential obstacle, and even those are simple in normal water conditions.
Crowds: Arethusa Falls is a popular destination, particularly on summer weekends and during fall foliage season. You won't have the falls to yourself on a Saturday in July. The parking lot is small (about 30 cars) and fills by late morning on busy days. Weekday mornings are the best time for a quieter experience.
Bugs: Mosquitoes and black flies are present from late May through early July, especially near the brook. Bug spray is worth packing during this period.
Wildlife: Typical White Mountains forest species: red squirrels, chipmunks, various woodpeckers, and the occasional moose (more commonly seen along Route 302 at dawn and dusk). Black bears are present in the area but rarely seen on this trail.
Cell service: Minimal to none along the trail. You may get a signal at the trailhead parking lot near Route 302.
Seasonal Notes
Spring (May through June): The best time to see the falls at peak volume. Snowmelt fills Bemis Brook, and the waterfall is at its most dramatic. The trail may be muddy and the brook crossings require more care. Bugs are at their worst.
Summer (July through August): The trail is dry and easy to walk. Water volume on the falls decreases through the season. By late August, the flow can be fairly thin. Crowds are heaviest.
Fall (September through October): Crawford Notch is spectacular during foliage season. The hardwoods along the trail turn gold and orange, usually peaking in early October. The falls have moderate flow. This is arguably the most photogenic time to visit, combining fall color with the waterfall backdrop.
Winter (November through April): The trail is hikeable in winter with snowshoes or microspikes, and the falls partially freeze into impressive ice columns. Winter visits are quieter and offer a completely different experience. Be aware that the approach on Route 302 through Crawford Notch can have difficult driving conditions. The parking area may not be plowed.
Tips
Visit in spring for water volume, fall for color. These are the two peak experiences at Arethusa Falls. Summer is the easiest time to visit but the least dramatic for the waterfall itself.
Bring a tripod for photos. If you want that silky, long-exposure waterfall shot, a small tripod makes all the difference. The rocky base area gives you plenty of spots to set up.
Wear waterproof footwear. The brook crossings and the mist at the base of the falls mean your feet will get damp at some point. Waterproof trail runners or hiking boots keep you comfortable.
Pack a lunch. The base of the falls is a great spot to sit and eat. There are enough flat rocks for several groups to spread out.
Don't underestimate the Frankenstein Cliff extension. It adds real distance and elevation to what is otherwise a short hike. If you're hiking with young children or anyone with limited experience, the falls alone are plenty rewarding.
Dogs are welcome on leash. The trail is dog-friendly, and most dogs handle the brook crossings without trouble.
Getting There
The Arethusa Falls trailhead is on Route 302 in Crawford Notch State Park, about 15 miles northwest of North Conway and 20 miles east of Twin Mountain. From Boston, take I-93 North to Route 3 to Route 302 East through Twin Mountain and Crawford Notch. The drive is about 2 hours and 45 minutes. Alternatively, from North Conway, take Route 302 West for about 15 miles. The trailhead is on the south (left) side of the road, marked with a brown WMNF sign.
The parking lot is small. On summer and fall weekends, plan to arrive before 10 AM or visit on a weekday. There's no overflow parking, and roadside parking on Route 302 is limited and can result in a ticket.
Nearest services: the Willey House snack bar (seasonal, about 5 miles north on Route 302) has drinks and basic food. For full services, Bartlett and Glen are about 10 miles east, and Twin Mountain is about 20 miles west. North Conway, with its full range of restaurants, shops, and grocery stores, is about 25 minutes east. For visitors combining this with a summit hike, Crawford Path to Mount Washington is a short drive west on Route 302 and represents the full spectrum of White Mountains hiking from this notch. Lonesome Lake in Franconia Notch, about 30 minutes north, is the best easy-to-moderate option in the region if Arethusa Falls whets the appetite for more. The America the Beautiful pass is accepted at the WMNF day-use parking lots in the area. For hikers exploring East Coast forests more broadly, the George Washington and Jefferson National Forests in Virginia share the same ancient Appalachian character as the White Mountains.
