Ordnance Survey's OS Pathfinder guidebooks contain 28 'Outstanding Circular Walks', from 4km up to 20km and are a great way to discover some of the best an area has to offer.
Each OS Pathfinder walk includes a difficulty rating and detailed route information using Ordnance Survey's clear, large-scale OS Explorer and OS Outdoor Leisure map extracts at 1:25,000.
The relevant OS Explorer/OL and 1:50,000-scale Landranger sheet numbers are shown in the information panel for each walk in every guide for added compatibility with your OS map collection.
