Ordnance Survey maps have been used and trusted by outdoor enthusiasts since the 1800s. OS surveyors have logged 460 million geographical features in Britain; with maps displaying key navigational info like contours, peak names, cliffs, crags, footpaths, bridleways, campsites – and pubs!
Not all maps are equal. OS maps show finer details that other maps miss.
Free maps often mark hills and mountains as flat green blobs with little detail; but OS maps illustrate concise locations of every footpath, stream, spring, forest, bog, fence, peak, and much more.
For the map geeks: we've seamlessly stiched together two navigation-ready map scales (1:25,000 and 1:50,000) that you can switch between easily by zooming in and out.
