26 wildfires on Pacific Crest Trail since 2018, causing 1,700 miles closure and impacting hiker navigation.

26 wildfires on Pacific Crest Trail (PCT) this year, with 1,700 miles closed temporarily since 2018 due to fires (250 miles burned). Unpredictable and longer wildfire season impacts hikers, who must navigate closures, skip sections or use reroutes. The Pacific Crest Trail Association offers a smartphone app for tracking wildfire closures, while "trail angels" assist stranded hikers. Extreme temperatures from climate change and fire suppression efforts contribute to the fires and other climate impacts on the trail.
