The Kilkenny Ridge Traverse is a moderate 2-3 day, 27-mile scenic traverse of some of the wildest and remote scenery in the White Mountains. It’s a particularly attractive route for backpackers interested in avoiding the crowds of day hikers who frequent the southern and central Whites. Bearded trees, their branches, and trunks festooned with moss and fungus line the ridgeline, battered by wind and storms. Open ledges and summits provide magnificent views of the entire ridge as it undulates north to south, past vast stands of forest shrouded in mist and cloud, with scant evidence of a human presence.
Hikers climb two White Mountain 4000-footers, Mt Cabot and Mt Waumbek, in addition to several smaller peaks called The Bulge, The Horn, and Mt Starr King, at the south end of the route. Side trips to a narrow canyon named the Devil’s Hopyard, Roger’s Ledge, Unknown Pond, and the Mt Cabot Fire Warden’s Cabin add to the novelty of this less-visited region.Kilkenny Ridge Traverse Guidebook

MapsThe Appalachian Mountain Club publishes the best maps for the White Mountains and I’d recommend buying the complete AMC White Mountain Waterproof Map Set. It contains three waterproof maps (2 regions per map) although you only need carry one or two on any trip. I also use GPS apps for navigating, but these maps contain relevant trail, shelter and topographic information that is often not included in electronic maps. More detailed trail descriptions can also be found in the AMC White Mountain Guide, which is considered the hiking bible for the region. It includes detailed driving directions to remote trailheads and is indipensible for navigating to them, especially when you're out of cell tower range. Take photos of the pages you need using your phone for easy reference, instead of carrying the entire book with you on hikes.
Navigation AppsI also recommend purchasing a GPS Phone App such as Far Out's White Mountain National Forest Guide, which lists most of the trails, trailheads, shelters, campsites, views, and water sources in the White Mountains National Forest. GaiaGPS is another GPS Phone App, which is stronger in terms of topographic map coverage for the White Mountains but does not have as much information about trailheads, shelters, campsites, views, and water sources. I use both frequently.
South Pond Recreation Area: (From the White Mountain Guide 3oth ed, p. 569) “South Pond Rd, the 1.8 miles access road to the South Pond Recreation Area and the northern terminus of the Kilkenny Ridge Trail, leaves NH 110 14.4 miles west of Berlin and 10 miles east of US 3 in Groveton, NH. Bear right at a fork 0.7 miles from NH110; just beyond this ford, there is a WMNF gate, which is locked from 8:00 pm to 10:00 am during the summer/fall season when the beach and picnic area are open. A fee is charged for day use, although in the past there has been no charge for parking of hikers’ vehicles with a WMNF parking pass. Hikers should park in one of the first two lots on the left past the gatehouse. When the beach and picnic area are not open, the gate is usually locked necessitating a 1.1-mile walk to the start of the trail. (Park outside the gate, not blocking it, with all wheels off the road/pavement.) Foot travel is always permitted. Check with the Androscoggin Ranger District Office of the WMNF for details. ”
Starr King Trailhead: There is additional hiker parking across from the road leading to the Starr King Parking Lot along Rt 2 next to a stone monument.
The route follows the following trails in sequence. Refer to the AMC White Mountain Trail Map 6 – North Country, Mahoosuc Range (2017 ed), which is the best waterproof map available for this region, although I’d recommend buying the complete AMC White Mountain Waterproof Map Set (2017 ed) rather than one map at a time. More detailed trail descriptions can be found in the AMC White Mountain Guide (2017 ed), which is considered the hiking bible for the region. Take photos of the pages using your phone for easy reference, instead of carrying the entire book with you on hikes.

- USFS Cabot Firewarden’s Cabin (Free) – There is an outhouse and space for 8 on bunks in the cabin. It’s not exactly super clean inside with peeling paint and assorted debris, but you can sleep inside in a pinch. I did it once myself.
Natural water sources are plentiful in the White Mountains although you may need to descend to them from ridgelines along side trails if you run short. In any case, carry a detailed topographic map with you and don’t rely on the overview map provided with this trip description to find water sources. Guthook Guides does not have a map of the North Country yet (as of 3/18), so you’ll need to rely on the USGS maps in the Gaia Smartphone App or a GPS Receiver if you want digital mapping support. While the topographic information found on USGS maps for this area is quite accurate, be aware that the trail information is frequently out of date or omitted. Carrying the AMC maps listed above is really your best option.
There are also several dry stretches along this route where it may be prudent to carry extra water. These include the stretch of trail between Unknown Pond and the York Pond Trail (the spring below Mt Cabot is difficult to locate and may be dry) and between the York Pond Trail and the Starr King Trailhead. If you don’t find water directly on the Kilkenny Trail, it’s usually just a short distance down one of these side trails.
This route experiences frequent blowdowns (trees knocked over by wind and snow) in winter, which may obscure the trail each spring, before trail crews can remove them. The greatest damage usually occurs along the stretch from the Kilkenny Ridge Trail/York Pond Trail junction south to Mt Waumbek. The trail is usually quite obvious despite these obstacles and blazed in yellow. Other than that, this route is almost entirely below treeline and well protected from the weather.
On the Trail
The Kilkenny Ridge Trail starts at the south end of the South Pond Recreation Area. The trail enters the woods and quickly comes to a junction with the Devil’s Hopyard Trail. This side trail leads to a gorge with steep sidewalls and “huge boulders set in picturesque confusion.” While not up to the caliber of Mahoosuc Notch farther north (also in the White Mountains), it is still a fun diversion and provides one with a first glimpse of the unusual foliage and scenery found along the rest of the Kilkenny Ridge Trail.
After you’ve hiked to the end of the Devil’s Hopyard, retrace your steps to the Kilkenny Ridge Trail junction and continue south. Continue through birch forest before climbing moderately to Rogers Ledge at 5.3 miles, a large south-facing cliff with a huge view of the Pliny Range to your right. You can even the see high peaks of Presidential Range from this vantage point, far to the south, on a clear day.
Descending Rogers Ledge, you’ll pass a spur trail to the Roger’s Ledge campsite in 0.5 miles, followed shortly by the Mill Brook Trail Junction. Continue past it heading south along the Kilkenny Ridge Trail, entering a boggy area near Kilback Pond.
Hike over bog bridges before climbing the shoulder of Unknown Pond Peak, a 3500′ trail-less mountain before dropping down to the Unknown Pond Campsite at the junction of the Unknown Pond Trail. This pond is a pretty place to camp and a great place to watch the sunset over The Horn. However, camping is only permitted at the designated campsite and not within 0.25 miles of the pond or along its shore.
Return to the Kilkenny Ridge Trail which runs along the north side of the pond before climbing to The Horn and The Bulge, two distinct viewpoints before Mt Cabot. A short spur trail leads to The Horn, which is topped by a rocky ledge. The best way to climb it is around the back side, although it can be a difficult solo scramble.
Retrace your steps to the Kilkenny Ridge Trail and resume hiking south to the summit of The Bulge, before climbing steeply to Mt Cabot, passing a summit sign at 10.8 miles. Beyond the summit, the trail passes a side path that leads to an unreliable and often hard-to-find spring (it’s best not to count on this water source) before arriving at the former Mt Cabot Fire Wardens Cabin.
The interior of this cabin has two rooms: a kitchen eating area with a table and a small bunk room with space for 4-6. While you can sleep in the cabin, most people just stop in to sit down and have a snack out of the weather or hang out on the porch. There’s also a nearby privy. There’s been a rain barrel situated outside in the cabin in the past, but I’d be very hesitant to drink water out of it, even filtered water.
Continue along the Kilkenny Ridge Trail, descending by switchbacks, passing the unmaintained Mt Cabot Trail (which has been closed in a landowner dispute), to a junction with the Bunnell Notch Trail. Continue right, climbing Terrace Mtn, passing a short spur trail to its southernmost peak (3665′), before dropping down into Willard Notch and the York Pond Trail junction. There is a primitive campsite just before the junction on the right (see the White Mountain Guide, p. 573) near a small brook.
Passing through the junction, continue heading south towards North, Middle, and South Weeks Mountains, passing through fern carpeted forest and moss-covered trees. The forest here is unlike any other area in the White Mountains.
There is an intermittent stream south of North Weeks, but that’s the only potential source of water along this section of trail until the bottom of the Starr King trail. Continue along the ridge to Mt Waumbek at 22.2 miles. While the summit is viewless, there is a small, east-facing opening just north of the summit, with a view of the Crescent Range near Randolph, NH.
The Kilkenny Ridge Trail ends on Mt Waumbek in a typical New England fashion, far from a road or trailhead. Continue straight (south) along the Starr King Trail toward Jefferson, NH, reaching the summit of Starr King Mountain (3907′) in 1 mile. This peak is named after Thomas Starr King, author of The White Hills: Their Legends, Landscape, and Poetry, an influential description of the natural history of the White Mountains published in 1859.
While Mt Starr King has a view, it’s probably best known for the stone chimney on its summit, the remains of an old cabin. From the summit, continue south, through forest as the trail drops gradually and soon parallels a noisy mountain stream that empties into the Israel River. Near the bottom of the trail, you’ll pass an old stone well, before arriving at the trailhead parking lot and the end of this journey.
