North and South Kinsman only; Winter:
Kinsman Trail as Kevin described. The only issue with this trail is finding the trailhead and parking. See Dave Metsky’s
trip report for directions and photos of the trailhead area.
OR
From Lafayette Place take Lonesome Lake and Fishin Jimmy Trails to Kinsman Ridge Trail. Return the same way.
If you want to add Cannon in the winter, it would be a long day. I would ascend Cannon first as the very steep section at the north end of the Kinsman Ridge Trail south of Cannon might be easier negotiated via descent than by ascent. At least that’s my opinion of it the times I have done it in the winter. YMMV. Continue south on Kinsman Ridge Trail to the Kinsmans and descend via Fishin Jimmy Trail and Lonesome Lake Trail to Lafayette Place. If you have a second car you could ascend Cannon via the Kinsman Ridge Trail out of the Cannon Mtn ski area parking lot. Keep in mind that the Kinsman Ridge Trail from the Hi-Cannon Trail to Kinsman Junction may not be broken out in the winter. Not many people do all three peaks in a winter’s day.
North and South Kinsman only; Non-Winter:
Kinsman Ridge Trail starting in Kinsman Notch (Rte 112). Park in the same lot you would for Beaver Brook Trail up Mt Moosilauke. Nice views from Mt Wolf and other outlooks, nice waterfalls and cascades, Harrington Pond and the open slopes south of South Kinsman all make this a wonderful hike. You can descend via Kinsman Pond and Cascade Brook Trails to the Basin parking area. If you add Cannon, descend to Lafayette Place. You will need a car spot.
OR
Ascend the Basin , Cascade Brook and Kinsman Pond Trails to Kinsman Junction and then take the Kinsman Ridge Trail to the Kinsmans. Return the same way. If you add Cannon, take the Kinsman Ridge Trail north to Cannon and descend to Lafayette Place via Hi-Cannon Trail. You will need a car spot for the latter.
Have fun.
