The British Mountain Maps display the detailed information clearly, including colour shading for easy identification of mountains, hills and valleys. Snowdonia North is written in both English and Welsh / Cymraeg and is half the weight of a laminated map. Waterproof and tear- resistant, this is a necessity for a productive day in North Snowdonia. The reverse of the map includes enlargements of Snowdon and Tryfan, mountain incident and first aid advice and useful local phone numbers.
