First the good news. The Gateway Arch in St. Louis, Missouri, which feels more like a landmark, tops the list of safest national parks in the U.S. Now, the bad news. The nation’s most dangerous national park by this study’s metrics is North Cascades National Park in Washington.

Notes on Methodology

To determine these rankings, the company took into consideration factors like fatalities per million visitors, most common cause of fatalities, dangerous animals present in the park (and abundance of the animal within the park), highest and lowest average temperatures, record high and record low temperatures, average number of search-and-rescue (SAR) incidents per year, SAR incidents per million visitors, vertical relief in elevation, whether the park has cell service, and whether the park has Wi-Fi.

Each park received a score per safety factor, and then the company totaled the scores. The highest scores landed parks on the most dangerous list. The lowest scores landed parks on the safest list.
