For northbound thru-hikers, it is the beginning of the main challenges that go beyond enduring distance and time: in New Hampshire and Maine, rough or steep ground are more frequent and [[alpine climate|alpine]] conditions are found near summits and along ridges. The trail crosses 15 of the 48 [[four-thousand footers]] of New Hampshire, including {{convert|6288|ft|m|adj=on}} [[Mount Washington (New Hampshire)|Mount Washington]], the highest point of the AT north of Tennessee and most topographically prominent peak in eastern North America. The trail passes within half a mile of 9 additional 4000-footer peaks in the Whites (one summit is only 60 yards from the trail). Entering the alpine zone on the summit of [[Mount Pierce (New Hampshire)|Mount Pierce]], from the south, the trail continues in alpine or near-alpine scrub continuously along the high Presidential ridge until descending the southeast flank of Mount Madison into the Great Gulf Wilderness over 12 miles northward. This region is subject to extremes of weather with little natural shelter and only occasional human-made shelter from the elements. The threat of severe and cold conditions in the Presidentials and across the New Hampshire Section is present year-round and requires hikers' careful attention to weather forecasts and planning, provisions and gear.

The [[Dartmouth Outing Club]] maintains the Appalachian Trail from the Vermont state line past [[Mount Moosilauke]] to [[Kinsman Notch]], northwest of [[Woodstock, New Hampshire]], Randolph Mountain Club maintains 2.2 miles from Osgood Trail near Madison Hut to Edmands Col, with the [[Appalachian Mountain Club|AMC]] maintaining the remaining miles through the state.
