The White Mountains (a range in the northern Appalachian Mountains) cover a quarter of the state of New Hampshire, USA. We leaf peepers love the peak of autumn foliage around the first week of October. Along popular Kancamagus Highway (NH Route 112) in White Mountain National Forest, enjoy Sabbaday Falls, Albany Covered Bridge and Rocky Gorge Scenic Area on Swift River. Hike rocky UNH Loop Trail on Hedgehog Mountain for good views of the Sandwich Range Wilderness and Mount Passaconaway. Walk to Diana's Baths to see many beautiful pools and waterfalls along Lucy Brook on North Moat Mountain. See Mount Washington (6288 ft, highest in northeast USA) above Pinkham Notch on Vermont Route 16 in the Presidential Range. Further south near Holderness, walking up West Rattlesnake Mountain gives an impressive view of Squam Lake.
