Great Gulf Trail to Spaulding Lake (Great Gulf Wilderness)

Great Gulf Wilderness, White Mountain National Forest (Route 16, north of Pinkham Notch)

The Great Gulf is the deep cirque on the north side of Mt. Washington, walled in by Jefferson, Adams, Madison, and Clay. Wikipedia describes the 5,552-acre Great Gulf Wilderness, set aside in 1964, as “New Hampshire’s oldest and smallest wilderness area.” The Great Gulf Trail follows the West Branch of the Peabody River up the valley floor to Spaulding Lake, a tiny pond at the foot of the headwall.

The lower valley has designated campsites, so it works as a one-night trip, with the option of climbing the headwall to Mt. Washington.

The hike

SummitPost’s route description starts at the trailhead on Route 16, about two miles north of the Mount Washington Auto Road, and crosses the Peabody River on a suspension bridge shortly after. Ski-trail junctions come in the first mile and a half, and the wilderness boundary is about 1.6 miles in, just before the Osgood Trail junction. The Osgood Cutoff junction follows, then the first designated campsites.

Past the Madison Gulf Trail junction, the trail rock-hops Chandler Brook, then passes the Six Husbands and Wamsutta Trails. SummitPost describes waterfalls and cascades along the West Branch beyond, with Mt. Jefferson’s walls to the right. SectionHiker’s 2013 report notes repeated stream crossings and native brook trout in the river. The Sphinx Trail junction comes a little over a mile later, and Spaulding Lake about a mile beyond that, just below treeline at 4,228 feet. SectionHiker puts the lake about 6.5 miles from the road.

Above the lake, the trail climbs the headwall: about 1,600 feet in the last half mile to the Gulfside Trail at 5,925 feet, according to SectionHiker, then 0.4 mile across the Cog Railway tracks to the summit. SectionHiker called the route “a very dynamic rockfall,” found blazes fading near the top, and navigated by compass in mist. It advises against doing the above-treeline parts by headlamp.

AMC’s “Best Backpacking Trips in New England” turns the valley into a 19.3-mile loop: up the Great Gulf Trail and the headwall, north along the Gulfside Trail over Clay, Jefferson, Adams, and Madison, and back down the Osgood Trail, with more than 7,000 feet of gain. It notes that overnight sites are limited and names Madison Spring Hut and the Randolph Mountain Club’s Crag Camp as ridgeline options (see Crag Camp and Gray Knob). The same ridge is part of the Presidential Traverse.

Nearby, the Madison Gulf Trail bridge, which carries the Appalachian Trail over the West Branch, has been closed since 2025. Valley News reported that a replacement is complicated by wilderness rules limiting machinery, and the Appalachian Trail Conservancy warns that fording the river there is “a dangerous crossing in all but dry conditions.”

Tips

Camp low. Plan to stop at the designated sites in the lower and middle valley.
Respect the river. SummitPost warns against descending into the Gulf during spring runoff.
Treat the headwall as a scramble. Wet rock and loose talus slow everyone down; turn around in fog if you can’t follow the route.
Bring a canister or use the boxes. SectionHiker reports Forest Service bear boxes at several designated sites.
Keep the group small. Wilderness groups are limited to 10.

Camping

Great Gulf Wilderness rules, from the Forest Service’s White Mountain brochure: no wood or charcoal fires anywhere in the wilderness; no camping within 200 feet of any trail except at designated sites; and no camping within a quarter mile of the Great Gulf Trail between the Sphinx and Gulfside junctions. Above treeline, camping is allowed only on 2 feet of snow. Hiking and camping groups are limited to 10 people, and no permit is needed (Forest Service wilderness page). AMC’s trip guide puts it plainly: “No camping in Great Gulf above the Sphinx Trail.” SectionHiker says camping isn’t permitted beyond mile 5.6, and forum posters say the designated sites are marked with small wooden tent signs.

Inside Intel: In a Views from the Top forum thread, one poster called Clam Rock “the furthest established tentsite in the Great Gulf with a bear box.” Another described two signed designated sites just past the Six Husbands/Wamsutta junction, one on each side of the trail, with good water but no bear box; a poster who had camped there said the right-hand site worked well. SectionHiker’s author asks campers to skip the heavily impacted, non-designated sites higher up: “It’s a moral decision whether you camp at these or not.”

The Great Gulf headwall above Spaulding Lake:

Above Spaulding Lake the headwall climbs about 1,600 feet in the last half mile on rockfall and talus. Here is how to choke down and place your poles on a pitch that steep.
