You are looking for a magnetic micro cache of about 3 inches long that is just hidden off of a public footpath. The footpath itself is wheelchair accessible, however you need to (only momentarily) leave the tarmac of the path and cross over a very small grassy verge (which may be a little weedy) so beware of any pebbles and stones.
As this is on the main ring road you will not be able to park, so if you come by car, I would suggest that you park in one of the nearby roads such as Albert Road or Hardinge road, where parking is free for a short while and then walk back using the pedestrian crossings where necessary.
The cache is very small and please remember to replace it once found exactly where it came from as it has disappeared on several occasions. It has a new friendly guardian, but he will be sad if he is not put back in his hidey hole.
Oh and as usual, beware of muggles, they will be everywhere as it is on one of Ashford's busiest roads, so you may need to visit early morning or in the evening.
