Flume Gorge

Flume Gorge is a natural granite chasm at the base of Mount Liberty, where Flume Brook runs between walls that rise as high as 90 feet. The marked, one-way circuit is about two miles and 1.5 hours, with moderate uphill walking and stairs. This is a ticketed, seasonal walk rather than a quick roadside stop: come for close views of the rock, waterfalls, and covered bridges. The route is not wheelchair accessible.

The gorge is reached from Gilman Visitor Center on Daniel Webster Highway. Check in outside the building, then walk around it to the trail entrance. The public center has restrooms, a food court, and a gift shop, handy before or after the loop. Check the current ticket and entry arrangements before you drive over; walk-in access depends on availability.

The narrow passage is the main event. Boardwalk sections bring you close to mossy, lichen-speckled rock and the brook, while stairs climb through the tightest parts. The gorge itself extends about 800 feet; at its highest, the granite walls reach roughly 90 feet. Avalanche Falls drops about 45 feet, and its flow changes with water and weather conditions. On busy days the narrow walkway can bunch people together, so expect a managed, single-file visit rather than solitude.

The loop continues past Liberty Gorge, Table Rock, the Pool, glacial boulders, and several cascades. The optional Wolf Den passage is a narrow one-way squeeze that involves crouching and crawling; skip that section if it is uncomfortable. The rest of the circuit still gives you a full walk through the gorge landscape.

The red Flume Covered Bridge crosses the Pemigewasset River near the visitor area. Farther along, Sentinel Pine Bridge stands beside the Pool, where a huge pine was thrown across the cliffs by the 1938 hurricane. Its trunk became part of the landmark setting for the bridge and the pool below.

The gorge cuts through Conway granite, formed as molten rock cooled roughly 200 million years ago. Basalt later filled cracks in the granite; as the softer dikes wore away, they helped open fractures that water and frost continued to widen. The polished walls and broken boulders show both sides of that process: slow cracking and fast-moving water.

The traditional account dates the gorge's discovery to 1808, when 93-year-old Jess Guernsey, known as Aunt Jess, came across it while fishing near her family's homestead. Her family initially doubted what she had found; the story became part of the Flume's identity as visitors began making the trip to see it.
