Asheridge is just a couple of miles to the north-west of Chesham, in Bucks, England. Make sure you don't go up the Chartridge Road - you'll only get hopelessly lost. From St. Mary's Way, take the Bellingdon Road, and then the Asheridge Road. It's actually sign-posted reasonably well, so long as you look for Asheridge and not Chartridge!
