GPX Route Downloads


Simply click on the GPX link button for your chosen route to download the file. You can then open the GPX file using your chosen app – the downloaded file will be accessible from your downloads folder.


GPX (GPS eXchange Format) is used to describe waypoints, tracks and routes. The data contained in GPX files can be read by specialist apps designed for walkers and cyclists. The app shows a map with the GPX track overlaid. If the device running the app, typically a smartphone or tablet, has GPS it will show your current position. More sophisticated apps offer different types of maps (various OS formats, and aerial). They may also collect data about your activity in a similar way to fitness trackers.


The accuracy of a GPX file depends on how it was created.


A GPX track is created by actually walking the trail. An app collects GPS location data at frequent intervals and produces an accurate record of where you went, including any diversions from the planned route.


A GPX route is built on a computer by clicking on waypoints. The quality of a route depends on the number of waypoints entered, accuracy of entry, and the route reflecting what is actually on the ground. Unless the person creating the route has local knowledge it may not include diversions for obstructions, damaged paths or stiles, and so on.


The HoWL Trail GPX files are currently routes. They are being replaced by more accurate tracks as each section is walked again by the Trail Champions.


There are other file formats doing a similar job to GPX, such as KML. An app using one of these files should include instructions on its use. Online conversion utilities will move data from one format to another.


GPS Apps

There are many apps on the market, both free and paid for. We do not recommend any particular app but list some to consider. Ask around fellow walkers to see what works for them, and read reviews on the internet. Apps should come with a User Guide and FAQs to help you download and import the HoWL Trail GPX files.


OS Maps Online https://www.ordnancesurvey.co.uk/shop/os-maps-online.html is a subscription service giving access to all OS maps. GPX files can be imported and trails displayed on a range of devices including smartphones and PCs.
