Snowdon Maps and Access

As far as Snowdon Maps and Access go, the OS Explorer maps at 1:25,000 scale show access land that has a Right to Roam. However, this isn’t as important as you might think. As someone who walks often in Snowdonia, we noticed no changes to the way we plan our walks when this legislation was brought in a few years ago. Access in Eryri has been good thanks to efforts of the National Park and local landowners.

The pink Landranger maps don’t show the right to roam areas, but we think they lack detail compared to the Explorer maps. Harvey maps do a 1:40,000 Mountain map that covers most of North Snowdonia. It’s an excellent map that has just enough information, but suffers as it’s a non-standard scale and can be awkward to measure distances on the map. While they’ve been coloured in to show height more effectively than the OS maps, they have contours at 15m intervals, rather than the standard 10m which can be confusing.

If you haven’t used British OS maps before, then rest assured that the quality of the maps place them amongst the world’s best. You can even get them for viewing on your PC, with the likes of Tracklogs and Memory Maps or their very own Ordnance Survey Maps.

You can plan your route on there and then transfer your route to a GPS device. Navigating by GPS can often be quicker, and we find it useful for the GPS to beep whenever you pass a waypoint – meaning we’re still on track. GPSs are only an aid to navigation and should be used as such.

Remember that the GPS files for all the routes up Snowdon are available on this site for you to download and load onto your device FREE of charge!
