Once you have the bug, you’ll be after a ‘swimming map’. This is the book that provides it, a practical guide to the 150 best and more importantly hidden bits of wild water. Waterfalls, rivers and lakes are all covered. I’ve found some very picturesque and romantic places because of it, based holidays around it and take it on other journeys just in case I dive past one he’s recommended. Worth every penny if you’re keen to have a waterfall or weir all to yourself.
