A common route climbs to Little Haystack, then follows the Franconia Ridge Trail over Lincoln and onward toward Lafayette before descending. The ridge section is roughly two miles of open, high-elevation walking, with broad views across the White Mountains and down into Franconia Notch. It is beautiful, but weather can change quickly up there; treat the exposed traverse as the serious part of the day, not an afterthought.
For a clear view of Lincoln's rocky crest, look back from Little Haystack. The boulders along the ridge make a useful foreground and show the scale of the peak; stay on the established tread rather than stepping onto the fragile alpine plants.
