  • KML/KMZ files can be opened in Google Earth, and many smartphone apps.
  • GPX files can be opened by most GPS software apps when KMZ cannot. Note, GPX files do not contain custom colours and icons that we use on our maps; all tracks and icons will appear the same colours and styles. We recommend using KMZ instead when possible.
  • GPX-Garmin are GPX files that we have optimized for older Garmin units that only display tracks that contain 500 points or less (such as Garmin eTrex units).

Visit our GPS & Navigation page for instructions of how to use your smartphone as a GPS device (even when outside of data coverage) or how to import data to your Garmin unit.

About the Journey: 

There are only superlatives to express the experience taking in the Othello tunnels and its canyon.  No one leaves this area unimpressed.  The loop allows one to take a trail, once part of the Brigade Trail, above the tunnel area.  Expect the latter to be a rugged trail and requiring quite a bit of climbing.  Of course the trail through the tunnels was once a railroad and therefore the grade is less than two percent.  The distance may seem short but because of the climbing it will take extra time.  Allow 2.5 to 3 hours.
