Hi-Cannon Trail

Overview

This is Cannon Mountain’s punchy, view-packed ascent. The classic loop (TOTAL 4.9 miles, about 2,335 feet of gain) uses a short connector on Lonesome Lake Trail, climbs Hi-Cannon to Kinsman Ridge, tags the summit tower, then returns via Kinsman Ridge and Lonesome Lake. Expect relentless grades, rough footing, and a signature ladder/ledge section near the top. An out-and-back to the summit via Hi-Cannon is a slightly shorter option (~4.5 miles TOTAL) if you prefer to skip the steep loop descent.

Route

Start at Lafayette Place Campground (Lonesome Lake Trailhead). Hike ~0.4 miles to the signed Hi-Cannon junction and turn right. Hi-Cannon climbs roughly 2 miles with tight switchbacks, ledgy outlooks, and a wooden ladder leading to an airy step. Reach Kinsman Ridge and go right about 0.4 miles to the summit and observation tower. For the loop, return to the Hi-Cannon junction and continue south on Kinsman Ridge ~0.4 miles to Lonesome Lake Trail, then descend past Lonesome Lake (optional short loop) back to the trailhead.

Highlights

• Multiple cliff-edge lookouts with big views to Franconia Ridge and the Northern Presidentials.
• A true summit experience on the observation tower.
• Lonesome Lake and the nearby hut make a scenic mid/late-hike pause for snacks when open. On operating days, the summit area also has seasonal facilities, and one-way tram rides down may be available.

What to Expect

This hike is strenuous and hands-on in places. The upper Hi-Cannon section is rough and rocky, and the loop’s Kinsman Ridge descent is extremely steep—expect slow, careful footwork and occasional hand use. Trail junctions are signed, but some blazes are worn; bring a map or GPS. Poles help on the eroded grades; gloves can make the ladder and ledges more comfortable.

Geology to Notice

Franconia Notch is a classic U-shaped, glaciated valley carved by ice that deepened an older river valley. You’ll hike over pink Conway Granite—jointed, fractured bedrock that forms Cannon’s cliffs and ledges—and pass talus born of post-glacial rockfall. This mountain also hosted the iconic Old Man of the Mountain, a natural granite profile that collapsed in 2003 after long weathering. Keep an eye out for glacial erratics and the broad, scoured forms that glaciers left behind.

Best Time to Hike

Aim for dry weather—wet slabs here get slick fast. Start early to beat crowds and parking pressure, especially on weekends. Shoulder seasons can bring ice; traction can be crucial. Summit lodge and tram operations vary by season, so don’t count on facilities or a ride down unless you’ve confirmed the day-of.

Tips

• Plan 3.5–5.5 hours for the loop depending on pace and stops.
• Ascend via Hi-Cannon and descend via Lonesome Lake to avoid downclimbing the ladder.
• This route is not suitable for most dogs due to the ladder and exposure. Wildlife is active here—give moose a wide berth and practice bear-aware habits.
