The Explorer OL map is very popular with outdoor enthusiasts and there are now 62 in the series covering all the National Parks and Areas Of Outstanding Natural Beauty. The 1:25,000 scale is great for runners, cyclists and walkers with loads of detail including contours, Rights of Way and campsites. The new releases now come with a Mobile Download so you can get a copy of your selected map on your Android or Apple device and save to memory. This allows you to pinpoint your location, route record and work with the map even when the mobile signal is down. All you need to do is use the unique code printed on the inside of the map cover and follow the instructions on the Ordnance Survey website.
