The Flume Gorge is 12 min up the road from us, at the mouth of Franconia Notch, and it is the walk we send most first-time guests on before they do anything else. An 800-foot granite gorge with a boardwalk running straight through the middle of it, a covered bridge on the way in, and a waterfall at the top. You can be standing in it half an hour after breakfast.
It is not a big-mountain hike. It is a two-mile loop on gravel and boardwalk that most people finish in about an hour and a half, and it gives you the Notch in miniature: the granite, the water, the cold air off the rock. It is also ticketed and seasonal, so a little planning the night before goes a long way. Here is what to know.
What you're walking into
The Flume is a natural gorge at the base of Mount Liberty, and it is narrow. The Conway granite walls run about 800 feet long, rise 70 to 90 feet over your head, and stand only 12 to 20 feet apart in places. A band of softer basalt once ran through that granite. Water and ice wore it away over a very long time and left the slot you walk through, with Flume Brook still running down the middle of it.
A woman named Jess Guernsey found it in 1808, fishing, at ninety-three years old. For most of the century after that, a boulder hung wedged between the walls overhead. A storm in 1883 swept it out, deepened the gorge, and left Avalanche Falls, a 45-foot drop, at the top. The boulder was never found.
The loop
It is a self-guided loop, roughly two miles, and it takes most people about an hour and a half. The footing is packed gravel to start, then a wooden boardwalk bolted to the rock through the gorge itself, then a trail back down. You climb a little under 500 feet over the whole thing, with stairs in the tight sections. It is steady work in a few spots, not technical, and any guest in decent shape will be fine.
You cross the Flume Covered Bridge early, built in 1886, over the Pemigewasset. The boardwalk then carries you up through the gorge to Avalanche Falls at the top. From there the loop passes the Sentinel Pine footbridge over the Pool, a deep green basin, and Table Rock, a long slab of granite the brook runs flat across, before dropping you back at the visitor center. Follow the signed direction; the climb through the gorge comes first, and the back half is easy downhill.
Tickets, timing, and parking
The Flume is run by New Hampshire State Parks, and it is ticketed and seasonal. Entry is timed, meaning you reserve a specific arrival window on a specific date, online, ahead of time. Book it. Walk-up availability is not guaranteed, and the good windows go first on summer weekends and all through foliage. You save a few dollars a ticket reserving online rather than at the gate anyway.
It runs from mid-spring into late fall, typically. In winter the crew pulls the boardwalks out of the gorge and it closes, so this is a warm-season walk. Hours shift with the season, so check the official NH State Parks site for current times before you go.
Parking and the visitor center sit right off I-93 at exit 34A, with restrooms, a cafe, and a gift shop. The lot is large and it still fills by mid-morning on a good weekend. Earlier is better, always.
From the lodge
We are 12 min south of the Flume, straight up the Notch, which is the whole reason it makes such a good first morning. Have a coffee in our lounge, drive up, walk the loop, and you are back before the afternoon gets going.
In foliage season, treat it like a dinner reservation: book your window the night before and be on the road by seven. The light in the gorge is better early and the crowds are thinner. Wear real shoes, because the boardwalk stays damp, and bring a layer, because the bottom of a granite slot runs cool even in August.
The Pemi Suite is the easy pick for this one, looking out toward the river the gorge feeds. If you want to make a morning of the whole Notch, the Basin is a short drive further up the parkway and pairs with the Flume nicely.
Where to stay for it
12 min north on I-93 to the Flume Visitor Center, exit 34A.
In foliage season, be on the road by seven. Parking fills by mid-morning and the timed windows sell out.
Book a mid-morning entry the night before, have coffee and oatmeal in our lounge first, and you will still be back for lunch.
The Pemi Suite is the natural match, and the Basin makes an easy second stop on the same drive.
