Offa’s Dyke National Trail GPS Data

Having just received all the Viewranger OS (Ordnance Survey) maps for the Offa’s Dyke National Trail on my N95 mobile phone, I decided to make a start creating the GPS routes in Viewranger to get a better feel for the trail.

I have broken down the trail into the same legs used in The National Trail Guides (in reverse from North to South) – these will probably not be how we walk the route – but is a good starting point.

You can download the GPS data for each leg from the table below. I have also given the length, height gain / loss and maximum height for each leg.

UPDATE: Due to the blog move, these files are no longer available to download – if you would like to receive them, please use the contact form at the bottom.

(slight disclaimer – I have tried to make the routes follow Offa’s Dyke trail as accurately as possible, however there may be some inaccuracies. If you spot any problems with the files, please let me know)

[UPDATE: The downloads are no longer available, but you can download them from:]

Leg Length (miles) Height Gain (ft) Height Loss (ft) Max Height (ft) GPS File
Prestatyn to Bodfari 12.1 2458 2274 861
Bodfari to Llandegla 17.5 4205 3574 1784
Llandegla to Chirk Mill * 15.7 2430 2884 1611
Chirk Mill to Llanymynech 13.9 2538 2645 1241
Llanymtnech to Buttington Bridge 10.4 243 284 273
Buttington Bridge to Brompton Crossroads 12.1 1891 1646 1345
Brompton Crossroads to Knighton 15.0 3652 3486 1401
Knighton to Kington 13.5 2419 2484 2484
Kington to Hay 15.0 2104 2349 1355
Hay to Pandy 16.0 2503 2451 2300
Pandy to Monmouth ** 16.0 1629 1947 727
Monmouth to Sedbury Cliffs 19.4 3627 3629 823
TOTALS 176.6 29699 29653 2484

* This route uses the alternative permissive route through the grounds of Chirk Castle (April to September)

** This route follows the Wye (rather than St. Briavels Common)

The next plan is to put these routes into Google Earth, along with other key points of interest, like castles, campsites etc.
