National 3 Peaks Challenge Maps. Ben Nevis, Scafell Pike and Snowdon at 20k scale. Waterproof, tearproof and 100% recyclable 820mm by 420mm double sided map sheet. Taking OS mapping at 50k scale we expand the mapping to produce 20k scale maps of the three challenge peaks, Ben Nevis, Scafell Pike and Snowdon. By expanding the OS mapping the features of names, roads, tracks and trails are more than doubled in size making them easier to read under Challenge conditions. We then add the Challenge Routes, specially highlighted to make them stand out against the OS map background information and add in additional information that will help your challenge. Each map covers the region to show the access roads as well as the walking routes. Ben Nevis includes the Glen Nevis Information Centre starting point and Glen Nevis Youth Hostel starting point. Scafell Pike includes the Wasdale and Seathwaite Challenge Routes. Snowdon includes the Pyg Track, Miners Track and Llamberis Challenge Routes. Each peak is a 420mm by 420mm OSlike map mounted on a double sided map sheet of 840mm by 420mm. The map designs are then printed on a 100 micron plastic substrate using UV cured inks on the UK's only press capable of using this latest technology. The result is a lightweight map that is both waterproof and tearproof, and fully recyclable, that will survive anything your 3 Peaks Challenge can throw at it and afterwards will fold up like new.
