GDT App logoThe Great Divide Trail App by Atlas Guides is a GPS map-based hiking guide for smartphones and tablets. The App works in airplane mode. No mobile service or internet is required after initial setup. The app uses your device’s built-in GPS and downloaded topographic maps.

The Great Divide Trail Guide is a free download from the “Guthook Guides” app with in-app purchases: Download a fully functional version of the App that includes the 25-km portion of the Great Divide Trail from its southern terminus at the Canada-US border to Cameron Lake in Waterton Lakes National Park.

The rest of the GDT is available via in-app purchases:

  • Each section of the GDT (A – G) is available for individual purchase: CAD$5.49 / USD$3.99 per section
  • Or take advantage of the “thru-hiker discount” and purchase the entire trail for a 35% savings: CAD$24.99 / USD$17.99

Note that a portion of every sale of the App will go to the Great Divide Trail Association to maintain and improve the trail. Special thanks to River Taig for all of his amazing work to map the GDT and create the data-set that this App is based on!

The App is available on iPhone and iPad via the iTunes App Store and Android mobile devices from the Google Play Store.
