Thru‑hiking debate goes viral

A social post tying solo thru-hiking to “adult daycare” and hormonal birth control turned a niche trail argument into a broad online fight this month. (x.com) The post pointed to long solo walks on the Pacific Crest Trail and Appalachian Trail and singled out one woman’s Mexico-to-Canada trek as evidence in a wider argument about fear, safety, and who should attempt these hikes alone. (x.com) Thru-hiking means covering an entire long trail in one continuous trip. The Appalachian Trail Conservancy says the Appalachian Trail runs more than 2,190 miles, most thru-hikes take about six months, and only about one in three thru-hikers finish. (appalachiantrail.org) The Pacific Crest Trail uses a permit system for long trips of 500 miles or more, and the Pacific Crest Trail Association says hikers need separate local permits in some areas if they are not using the long-distance permit. Backpacker reported the association releases 50 northbound start permits per day for March 1 through May 31. (pcta.org; backpacker.com) The birth-control claim in the post came from a recent fear-learning study, not from trail research. A 2025 paper in *Neuropsychopharmacology* tested how hormonal status and oral-contraceptive use affected fear responses in laboratory settings, including responses to safe contexts. (nature.com) That study did not test thru-hikers, trail decision-making, or backcountry accident rates. A 2023 review in *Progress in Neurobiology* said research on hormonal contraceptives and mental health is mixed and called for more individualized, better-designed studies. (nature.com; sciencedirect.com) Trail groups’ own surveys show many hikers are looking for solitude as much as social life. In the Appalachian Trail Conservancy’s 2024 long-distance hiker survey, 61% of respondents said solitude was important to their experience and 59% said they valued the trail’s wild character more than its social aspects. (appalachiantrail.org) The same surveys also show these trips are expensive and structured, not casual escapes. Halfway Anywhere’s 2024 Pacific Crest Trail survey collected 764 responses, and Backpacker said the average reported cost of a Pacific Crest Trail thru-hike had climbed above $10,000. (halfwayanywhere.com; backpacker.com) On the Appalachian Trail, the Conservancy’s 2024 survey drew 747 responses from hikers who registered through its voluntary ATCamp system. In 2025, Backpacker reported thru-hike registrations were running nearly 30% below the same point in 2024, suggesting interest can swing even before people reach the trail. (appalachiantrail.org; backpacker.com) What spread online was less a dispute over mileage than a dispute over what solo hiking means: managed recreation, personal freedom, or avoidable risk. The trails themselves still demand permits, money, months of time, and a completion rate low enough that even critics and defenders agree they are not easy walks. (pcta.org; appalachiantrail.org)
