NPS Emphasizes Group Fitness Levels

The National Park Service's advice is backed by frequent search and rescue (SAR) operations where underestimation of a trail's difficulty is a key factor. Hiking is the leading activity requiring SAR assistance in national parks, accounting for nearly half of all incidents. Factors like fatigue, inadequate equipment, and errors in judgment are commonly cited contributing factors in these emergencies. Many of the "popular" trails shared online, like Glacier's Highline Trail, present significant risks. While offering stunning views, the Highline Trail features narrow sections with steep drop-offs of hundreds of feet, and there have been multiple fatal falls. The trail's 11.8-mile length and exposure at high elevations demand serious respect for weather and personal fitness. Zion's Narrows, another fan favorite, requires hikers to wade and sometimes swim in the Virgin River. This unique environment poses risks of hypothermia, even in warmer months, and the canyon is dangerously prone to flash floods which can be deadly. A permitted 16-mile top-down route through The Narrows turned fatal for a 31-year-old woman who succumbed to hypothermia. The hike to Delicate Arch in Arches National Park is only a 3-mile roundtrip, but it involves a strenuous 480-foot climb on exposed slickrock with no shade, leading to frequent rescues. In winter, this same rock can become treacherous with ice, which contributed to a tragic incident where two family members fell to their deaths. Even trails requiring special access, like the Fiery Furnace or Canyonlands' Joint Trail, are not to be underestimated. The Fiery Furnace is a maze-like labyrinth requiring a permit or a ranger guide to navigate its scrambles and narrow passages. The 10.7-mile Chesler Park Loop, which includes the Joint Trail, is rated as strenuous, winding through deep rock fractures in a remote section of the park.
