AllTrails

A record-high of 63 million people hiked in the U.S. in 2024, according to the Outdoor Industry Association—an increase of 5 million in just four years. Helping explorers of all skill levels navigate terrain is AllTrails, a platform offering more than 500,000 verified trail maps for hiking, biking, and running that saw its global users balloon from 10 million in 2019 to more than 95 million in March 2026. Though a version of the AllTrails app is free, the company bolstered its paid-subscription offerings in 2025 to include expanded offline maps, custom routes (allowing users to modify existing trails), reporting on conditions like weather and mosquito activity, and an AI-powered feature that identifies plants and insects. “We want to help people find their trail, plan their trip,” CEO Liz Hamren says, “Then, when you're out on the trail, how do we make that experience great.” AllTrails also announced partnerships with T-Mobile (to provide satellite service in dead zones), Apple (in-app Apple Intelligence integration), and OpenAI (enabling users to access trail maps directly in ChatGPT). In 2026, AllTrails continues to add new maps in over 200 countries worldwide, plus real-time updates on trail conditions and closures using data from more than 800 partner agencies, nonprofits, and community organizations.
