Getting started with GPX files – A guide for walkers

Whether you’re planning your own walking adventure or downloading a ready-made route, GPX files are your best friend when navigating the great outdoors.

In this guide, we’ll walk you through what GPX files are, how to use them with OS Maps (both app and desktop), and how to transfer them to a GPS unit or GPS watch.

1. What is a .gpx file?

A GPX file (short for GPS Exchange Format) is a universal file type that stores location data like routes, tracks, and waypoints. It can be created manually using mapping tools like the OS Maps app or generated automatically when recording a walk on a GPS device.

These files use GPS coordinates to plot –

Waypoints – Specific points of interest (like a summit or viewpoint)

Routes – A series of waypoints connected to guide your journey

Tracks – A breadcrumb trail of where you’ve walked, often automatically recorded by a GPS unit

The beauty of GPX files is their flexibility, they can be opened, edited, and shared across a variety of platforms and devices. Whether you’re using the Ordnance Survey app, a Garmin GPS unit, or planning online, GPX files help keep you on track.

2. Recommended Websites to Find GPX Files

Every route created on the OS Maps App has a downloadable GPX File available for premium members. Just one of the many benefits to the paid for version of OS Maps.

There are many reputable websites offering free (and often user-tested) GPX downloads. Here are a few we have found useful –

Where to find GPX Files for Long Distance Trails – recommended websites

National Trails – Official GPX files for all UK national trails

Saturday Walkers Club – Detailed London and Southeast routes

The Walking Englishman – Popular for well-annotated long-distance walks

GPS Routes – A large archive of both walking and cycling routes

GPX Library (GPS Training) – Members’ library of handpicked routes

Where to find GPX Files for Day Walks – recommended websites

Walk Highlands – Fantastic for exploring Scotland

Walking World – Extensive library, includes maps and GPX

Harold Street – A classic resource for hillwalkers

3. If downloading from third-party websites, bear this in mind

Not all GPX files are created equal. Before heading out, it’s worth checking:

Is it a route, track or course?
Route: A planned line made up of waypoints. Often gives directions or turns but may not follow exact paths on the ground.

Track: A recording of someone’s actual walk, giving a more accurate path. Useful if you want to follow exactly in their footsteps.

Course: Often used for sports/fitness GPS watches, these can have pace or heart rate targets. Not always ideal for leisure walking.

Quality Check: Is it a reliable GPX file?
Has the file been tested or reviewed?

Does the route fit your experience level and conditions?

Is the start/end accessible by you, if you start and finishing point are too close together your GPS watch/ GPS unit can get a little confused?

Limitations – Some devices have limits on the number of route points or tracks they can store. GPX files with thousands of points may need simplifying (many apps can do this automatically).

4. How to Transfer GPX Files to Your GPS Unit or GPS Watch

Once you’ve got your GPX file, it’s time to get it on your device. Here’s how –

Using Your GPS Brand’s App

Most GPS watches or units come with a companion app or desktop software:

Garmin: Use Garmin Connect or Garmin Explore

Suunto: Use Suunto App

TwoNav: Use Land or Link App

Satmap: Use Satsync

In most cases:

Import the GPX file into the app or software

Sync your device, the route or track will appear on the unit

Using a USB Cable, often used for GPS units as not all use apps

If you’re working from a desktop:

Plug in your GPS device via USB

Open the device storage like a USB stick

Copy the GPX file into the appropriate folder (e.g. /Garmin/NewFiles or /Satmap/Routes)

Eject the device and check that the file appears under your routes or tracks

With OS Maps (Mobile & Desktop)

You can import and use GPX files directly in OS Maps:

Desktop: Login > My Routes > Import a GPX file

Mobile App: Open ‘Routes’ tab > Tap ‘+’ > ‘Import GPX’

Once imported, the route is available offline and can be followed with real-time tracking on the OS Maps app.

Top Tip:

Always double-check the GPX file before heading out, especially if it’s from a third-party site. Make sure it suits your ability, timeframe, and access points. And don’t forget to carry a paper map as backup!

5. Time to get started with GPX files

GPX files might sound technical at first, but they’re simply a digital way to plan, share, and follow routes, putting you in full control of your outdoor adventures.

Whether you’re mapping out a personal challenge, following in someone else’s footsteps, or just discovering a new place with confidence, GPX files help you make the most of every walk.

Combined with tools like OS Maps and a GPS device or watch, you can explore further, stay safe, and enjoy the countryside with added peace of mind. So go on, download a route, load it up, and step outside with confidence. Your next great walk is waiting.
