If you are going to Exmoor and want some top maps for showing trails/paths, then have a look at these locally designed waterproof maps by http://www.croydecycle.co.uk. The style is similar to Harveys, but at 1:12500. I've had the Porlock area map for a while and just got the new Horner and Dunkery one today which shows tonnes of trails I didn't know were there. They are remarkably detailed and have quite a lot of supplementary text like: "stream crossing tricky if heavy rain" and "Boneshaker on a bike".

Brill – ta for that!

Clink, If you're over that way, get me some. We should head over that way for a day.
