We have come to the unfortunate conclusion that the Halfmile Android and iPhone Apps will not be updated for the 2018 hiking season due to other commitments and lack of available time.

Halfmile Pacific Crest Trail Maps, GPS files, Google Earth Files, and Trail Notes have all been updated for 2018. Only the Smartphone Apps have not been updated. If hikers need to convert between 2015 mileages (still used by the Halfmile App) and 2018 mileages, a version of the Halfmile Trail Notes has been published that includes both 2015 and 2018 mileages.

What does this mean for 2018 Pacific Crest Trail hikers? Halfmile Smartphone Apps will continue to work, but hikers might notice:

  • Resupply and other information contained in the Halfmile Smartphone Apps may not be current and should be verified from other sources such as a phone call to the various locations or Halfmile Trail Notes.
  • The Sierra Buttes Reroute (starting near mile 1204), that was completed in the fall of 2017, is not included in the Halfmile app. This new route replaced about 4.4 miles of old trail with 6.9 miles of new trail.
  • Because the PCT is now 2.5 miles longer than the previous year, mileages in the Halfmile app north of about mile 1210 will be off by 2.5 miles.


    • Hikers needing an app that uses the latest Halfmile PCT data could consider Gaia GPS or other apps that import GPX files. It’s easy to import Halfmile data into these apps using the data at this web page.

    Halfmile data can be imported into the Gaia GPS or other smartphone apps.
