This is a Wherigo cache, which can only be found by downloading a Cartridge on to your GPSr or using an app on your phone. I have tested it with the Wherigo app on my android phone and it worked fine, and the Cartridge itself has been used for numerous caches around the world. You will need to download the Reverse Wherigo Cartridge created by -Waldmeister-, which is available to download here.
The Cartridge tells you how far away you are from the final cache hide, but not the direction in which you need to go. Once you start the Cartridge going, set it up by choosing your language and measurement unit. Then input that you want to Play (not Create) a Reverse Wherigo. Then input three sets of 6 numbers (see below) one at a time. You can then look in your Inventory for the Reverse Cache Box. Click on that to display the distance to the cache. The Cartridge keeps a tally of how many times you look at the Reverse Cache Box to get the distance, although it doesn't seem to matter if you look numerous times (as far as I have experienced).
Start at the way point posted on cache page: Here you will use the footpath sign "What is the name of walk on white footpath sign?" put this in the checker and you will have a set of numbers for the reverse wherigo.
Parking coordinates added to this page. Hope you enjoy these reverse wherigos which takes you on a nice walk with some good views. Don't forget the binoculars.
Keep hold of these numbers: if the cartridge crashes you will need to put them in again to continue. Once you complete the cartridge you will get a code so that you can create your own Reverse Wherigo anywhere you like, just make sure you tell Waldmeister about your cache.
Please don't say anything in your log that will give the direction or distance away.

The Little Bridges series was started by Stanthews in 2009 to highlight small footbridges in remote parts of Wiltshire. Since then, the series has been expanded by others all over the country and starting to spread fast. There is a stats listing, so you can see how many Little Bridges you have found, you can find it here: - Little Bridges Geocaching Series (littlebridgesseries.co.uk). If you would like to add to the series, please go to this site, on the tab Get Involved click number request and fill in the form. To qualify, the bridge must be a foot bridge too small for vehicles, please make sure your title exactly matches “Little Bridges # xxxx then the name” including spaces so it will get picked up and added to stats list.
