Ordnance Survey Outdoor Leisure and Explorer maps at 1:25,000 are recommended. Although the outlay is considerable at £7.99 each, (minimum of nine required), most are double sided. The latest edition was especially timed to show all public access land, and are better value than the 1:50,000 Landranger maps, which do not show enough detail and are all single sided. The 1:250,000 map of Wales gives the whole picture and is useful for planning and distant view identification.

Note 1 Explorer Map 151 is required for the nine miles from Cardiff Castle to the Rhymney Valley Ridgeway at Rudry. Alternatively there is an online OS Maps service provided by the Ordnance Survey where the missing section can be downloaded and printed in limited detail for FREE or in full detail by subscription.
Note 2 Explorer Map 214 is required for less than 3km of the route, just past the summit of Plynlimon. This could be walked using the guidebook only or the missing section can be printed using the OS Maps Service as above. A grid reference of SN814876 in the 'Search' field will get to the area and the map can be zoomed, positioned and printed.
Grid Numbering on 1:25,000 Maps
Ordnance Survey maps have grid numbers printed at 10km intervals along each axis. This means that a folded map in a map case has only about a 30% chance of having grid numbers visible on both axes. To avoid having to remove maps from the map case whenever a grid reference is required, it is recommended that repeat numbering is marked on the maps close to the route wherever necessary, before commencing the walk.
Free Maps from Ordnance Survey 'OS Maps' Website
The Ordnance Survey have now replaced their Getamap service by OS Maps.
There are three levels of access to the service giving different facilities as follows:
For those planning to walk the Cambrian Way, this could be a more economical way of obtaining maps of the route than buying paper maps and it may be worth paying the subscription fee for the convenience of printing customised map sections of the route. It must also be remembered that printer consumables add to the cost, and some printers are considerably more expensive to run than others. There is also the disadvantage that prints from inkjet printers can be ruined if they get wet, whereas those from laser printers are more durable.
Further information about OS Maps is available on the GPX File page by following the link below.
A set of GPX files of the Cambrian Way Route are available to download, and these can be imported into OS Maps or used in other mapping software or compatible GPS devices.
