An early example of an interest in hiking in the United States is Abel Crawford and his son Ethan's clearing of a trail to the summit of Mount Washington, New Hampshire in 1819. This 8.5-mile path is the oldest continually used hiking trail in the United States. The influence of British and European Romanticism reached North America through the transcendentalist movement, and both Ralph Waldo Emerson (1803–82) and Henry David Thoreau (1817-62) were important influences on the outdoors movement in North America. Thoreau's writing on nature and on walking include the posthumously published "Walking" (1862)". His earlier essay "A Walk to Wachusett" (1842) describes a four-day walking tour Thoreau took with a companion from Concord, Massachusetts to the summit of Mount Wachusett, Princeton, Massachusetts and back. In 1876 the Appalachian Mountain Club, America’s earliest recreation organization, was founded to protect the trails and mountains in the northeastern United States.

The Scottish-born, American naturalist John Muir (1838 –1914), was another important early advocate of the preservation of wilderness in the United States. He petitioned the U.S. Congress for the National Park bill that was passed in 1890, establishing Yosemite and Sequoia National Parks. The Sierra Club, which he founded, is now one of the most important conservation organizations in the United States. The spiritual quality and enthusiasm toward nature expressed in his writings inspired others, including presidents and congressmen, to take action to help preserve large areas of undeveloped countryside. He is today referred to as the "Father of the National Parks". In 1916, the National Park Service was created to protect national parks and monuments.

In 1921, Benton MacKaye, a forester, conceived the idea of the America's first National Trail, the Appalachian trail, and this was completed in August 1937, running from Sugarloaf Mountain in Maine to Georgia. The Pacific Crest Trail ("PCT") was first explored in the 1930s by the YMCA hiking groups and was eventually registered as a complete border to border trail from Mexico to Canada.
