Apple has added new hiking features to their Maps app on iOS 18, just months after declaring AllTrails the iPhone App of the Year. Users in the U.S. can now access and save thousands of hikes in all 63 national parks, as well as create and save their own custom walking routes. These features also include topographic maps on the iPhone, previously only available on the Apple Watch. While these features are mostly limited to the U.S., topographic maps are also available in Japan. iOS 18 is currently in beta and will be released in September.
