America’s national parks are beautiful—but they are also wild places that can be dangerous if you don’t follow outdoor recreation safety guidelines. Every year, people go missing or get hurt in national parks, but some national parks are deadlier than others.

Outdoor clothing company KÜHL decided to find out what the top ten most dangerous national parks in America are by analyzing data from all 63 national parks.

The study looked at statistics from the National Parks Service and data from Google Maps, and assigned each park a weighted score using the following criteria:

  • Number of total deaths from 2007-2024
  • Number of missing persons from 2007-2024
  • Frequency of search and rescue missions from 2013-2024
  • Number of visitors to each park from 2007-2023
  • Amount of trail closures, alerts, and cautions due to animal presence
  • Number of park rangers
  • Proximity to hospitals

    3. Be prepared with appropriate gear and adequate amounts of food and water.
