Flume Gorge Trail

The Flume Gorge Trail is a 2-mile, one-way walking loop from the Flume Visitor Center through the Flume, Liberty Gorge and the glacial Pool. People come to walk beside high granite walls and rushing water; if you want the famous gorge up close, this is the route that does it. Allow about 1½ to 2 hours. The short distance can fool you: most of the path is packed gravel, but the loop climbs and has stairs, boardwalks and several reasons to stop. Admission is paid and seasonal. Reserve a timed entry window ahead; walk-ins are accepted only when there is room.

Check in at the visitor center, then go around the building to join the trail. A useful way to pace it is about 0.7 mile to the Flume, 0.7 mile from there to the Pool, and 0.6 mile back. The first stretch is a shaded woodland walk down toward the Pemigewasset River. Near the first quarter mile, you cross the Flume Covered Bridge on its pedestrian walkway, then climb past Boulder Cabin toward Table Rock. Keep going after the main gorge: Liberty Gorge and the Pool are part of the named visitor route, not optional side trips.

Table Rock is a broad granite shelf where Flume Brook spreads across the stone. From there the gorge narrows into an 800-foot passage beneath granite walls as high as 90 feet. The walkway hugs the rock above the water, changing from gravel to boards, ramps and stairs. Avalanche Falls is the big payoff, with the water and cliff walls close around you. Take the stairs slowly when they’re wet, and expect the narrow viewpoints to bunch people up on busy days; leave time for a pause instead of trying to rush through.

Past the Flume, the path reaches Liberty Gorge and its smaller cascade, then opens onto the Pool, a deep basin in the Pemigewasset. It formed about 14,000 years ago, near the end of the Ice Age, as a glacial stream cut into the rock. The Sentinel Pine Covered Bridge crosses the river here. From the nearby overlook, frame the bridge with the dark water and granite banks rather than taking a tight bridge-only shot.

Just beyond the bridge, Wolf’s Den is an optional squeeze between boulders. You have to duck and crawl on hands and knees, but there’s a marked bypass and ladder for anyone who’d rather skip it. The return continues past glacial boulders before climbing back to the visitor center.

The Flume cuts through Conway granite. A dike of basalt filled a crack in the granite roughly 200 million years ago; the basalt wore away faster, leaving the narrow passage, while water and frost kept working the exposed rock. The Pool is much younger, a glacial feature rather than part of that ancient volcanic story.

There’s a human story too. The discovery story dates to 1808, when 93-year-old Jess Guernsey is said to have followed the sound of water while fishing and found the gorge. The Sentinel Pine Bridge carries another reminder of the landscape: the tree it’s named for was blown down in the 1938 hurricane, and its trunk was used in the bridge over the Pool.

Use the Flume Visitor Center lot off I‑93 Exit 34A; check in outside the main building, then follow the path around it to start. The center has restrooms, a food court and a gift shop, all at the start and finish rather than along the walk. Dogs are prohibited on the route, and it is not wheelchair accessible. If you want a free, quiet or flat path, choose another stop; the narrow gorge and stairs are the point here, and paid entry is part of the visit.
