4★ Lonesome Lake Route
10.0 mi out-and-back, medium/hard, gain 3,260 ft
AllTrails · GPX File · Directions

The dual peaks of Kinsman Mountain are set back from the main Interstate 93 thoroughfare and don't cast as dramatic a profile over Franconia Notch as Cannon Mountain and the Franconia Ridge. Despite this, the North and South Kinsman Mountain peaks more than qualify as 4,000 footers and a hike to the top provides plenty of drama along the way.

Most hikers will likely approach the mountain from the east, beginning with an easy trail to Lonesome Lake, providing you're prepared for a gently inclined thousand foot hillside walk. The lake is destination by itself, tempting swimmers to enjoy the waters along with mountain views in all directions. The AMC Lonesome Lake Hut on the west shores of the lake includes a lakefront deck, restroom and potable water along with overnight accommodations.

Beyond the lake and all the way to the twin Kinsman summits, the terrain becomes more difficult. We have categorized this trail as medium/hard to make hikers aware of the many short but steep granite boulders, rock scrambles and rock hopping required to negotiate the route.

Thankfully trail builders have incorporated occasional steps, ladders and other helpful trail furniture to help us on the way, but not in all cases. Wear the shoes with the most grip that you have, and be most careful on potentially slippery wooden surfaces. We really enjoyed the route and found the variety of terrain to be a lot of fun, but make sure you budget plenty of time on this ten mile trail, and expect some downhill sections to require just as much effort as they required when climbing upward.

Almost every viewpoint on the Lonesome Lake route faces east, and we've marked the best of them on our map, including some that are a little further along the trail beyond South Kinsman. More views are evident at the summit, though none that could be described as panoramic. Kinsman is often also a trap for clouds, so enjoy every view you can find.

Lonesome Lake is only available to those that hike in.

Another popular route to the summits of North and South Kinsman Mountain is from the west on the Kinsman Mountain Trail. We've linked to the AllTrails page for that route below, which they list as being an 8.2 mile out-and-back with 3,220 feet of elevation gain. Trailspotting will update this trail review once we've tackled this route for ourselves.

Driving directions linked above lead to the large Old Bridle Path parking area on the east side of Interstate 93, and the Lonesome Lake trail towards Kinsman Mountain is accessible by a trail under the freeway. This is the first parking opportunity if you are driving up from the South and the one with the greatest chances of finding an available spot. There are two other parking areas across the interstate (directions) and both are closer to the trailhead, but there is no connecting road under the freeway at this location and driving between the two sides requires four to five miles of additional driving.

The cairn is situated on rocky terrain with sparse vegetation. In the background, multiple mountain peaks are visible under the partly cloudy sky.
