This book introduces the pastime of trigpointing, with 25 walks in the Yorkshire Dales, each aimed at finding Ordnance Survey pillars.They're just pyramids of stone, nothing to right home about, but they're part of our heritage and worthy of our patronage. It's an excuse to get out in the fresh air and try out some new ground, with the objective of reaching the pillars adding a new dimension to the walking experience. The walks are for all ramblers, experienced or otherwise, some easy and others more challenging. Walk to all the best scenic viewpoints - from the top you can spot all the surrounding pillars. This book shows you how.
