With its exceptional level of detail and clarity, Ordnance Survey’s Explorer Map OL18 Harlech, Porthmadog and Y Bala is a favourite of walkers, climbers, mountain bikers, outdoor professionals and anyone else who needs to know exactly where they are. The 1:25,000 scale allows plenty of detail, and the squares of the National Grid allow every bit of Great Britain to be given its own unique reference number.

An abundance of features are displayed, including areas of interest, picnic spots, campsites and National Trails, along with National Park and Rights of Way information for England and Wales.

Once you have received the paper map you will also be able to download the electronic version to your iOS or Android smartphone or tablet for use with Ordnance Survey’s OS Maps app. To claim the download you will need the unique code hidden by the scratch-off panel on the inside cover of the map. Please note that once this code has been revealed we will no longer be able to accept the return of the map for a refund or exchange. This does not affect your statutory rights.
