GPX Files for Backpacking: Import, Export, and Why They Matter

If you’ve spent any time planning trips online, you’ve bumped into the file extension .gpx — and if you’re new to it, it can feel like a mysterious technical detail meant for someone else. It isn’t. GPX is the plain, universal language that lets your route move between the tools you plan with and the devices you navigate with. Understanding it is the difference between a route trapped in one app and a route you can carry into the field on whatever gets you home. Here’s what GPX is and how to actually use it.

What a GPX file is

GPX stands for GPS Exchange Format. It’s an open, standardized file type designed to hold geographic data — and because it’s a shared standard rather than any one company’s format, almost every mapping tool, GPS device, and navigation app can read and write it. That universality is the entire point.

A GPX file typically contains some combination of three things:

  • Waypoints — individual marked points, like a trailhead, a water source, a campsite, or a junction.
  • Tracks — a recorded breadcrumb trail of where someone actually walked, made of many closely spaced points.
  • Routes — a planned path defined by a sequence of points to follow.

In practice, backpackers care most about tracks and waypoints: the line of the trail you’ll follow, and the important spots along it.

Why it matters: no tool does everything

Here’s the core problem GPX solves. The tool that’s best for planning a trip on a big screen at home is often not the tool that’s best for navigating it on a small screen in the rain. You might design a route in one place, want the elevation profile from another, and prefer a specific app on your phone or a dedicated GPS unit for the trail. Without a common format, your route would be locked into wherever you first drew it.

GPX breaks that lock-in. Draw once, export a GPX, and import it anywhere. Your work moves with you instead of being stranded in a single app. It’s also how you use someone else’s route — download the GPX from a trip report or route database and load it into your own tools to study and follow.

The plan-then-navigate workflow

The way experienced backpackers use GPX usually looks like this:

  1. Plan at home. Draw or assemble your route in a full-featured planning tool where you can see the whole map, set daily segments, mark campsites and water, and read the elevation profile.
  2. Export a GPX. Save the finished route — track plus the waypoints that matter — as a single GPX file.
  3. Load it onto your field device. Import that GPX into your phone navigation app and/or a dedicated GPS unit, and download the offline maps for the area.
  4. Navigate offline. In the backcountry, follow the imported track. You’ll see your position relative to your planned line even with no cell signal, because GPS works independently of cellular service.

A planner like Trailfold fits the first two steps: you build the route and it exports a clean GPX you can carry into whatever app or device you navigate with. The point isn’t to replace your field navigation tool — it’s to feed it a solid plan.

Importing GPX into your tools

Bringing a GPX in is usually as simple as an “Import” button and choosing the file, but a couple of things smooth it out:

  • Tracks vs. routes: if a downloaded file gives you trouble, check whether it’s stored as a track or a route — some tools handle one better than the other, and occasionally you’ll want to convert between them.
  • Waypoint clutter: files from other people can carry dozens of stray waypoints. Clean out the ones you don’t need so your map stays readable.
  • Offline maps: importing the line is only half the job. Always download the underlying map tiles for the area before you lose signal, or you’ll have a track floating over a blank screen.

Exporting cleanly

When you export a route to carry into the field, a little tidiness pays off:

  • Keep the meaningful waypoints — campsites, water, key junctions, bailout points — and drop the noise.
  • Give waypoints clear names so “Camp 2” and “Spring — confirmed” mean something at 6 a.m.
  • Double-check the exported track actually matches your intended route before you rely on it, especially if you edited it after drawing.

GPX is a tool, not a replacement for skill

A track on a screen is enormously useful, but it doesn’t excuse you from carrying a paper map and compass and knowing how to use them. Phones die, get dropped in creeks, and freeze at altitude. GPS can also be wrong or lose its fix under heavy tree cover or in deep canyons. Treat your GPX as your primary convenience and your map and compass as the backup that never runs out of battery — that’s the ten-essentials mindset, not paranoia.

GPX is simply the common language that lets your route travel from the tool you plan with to the device that guides you. Learn to import and export it cleanly, adopt the plan-at-home, navigate-in-the-field workflow, and keep analog backup in your pack. Once it clicks, a .gpx file stops being a mysterious attachment and becomes one of the most useful things you carry.
