You can approach this footpath from either Upper Swainswick or Woolley. I approached from Upper Swainswick. If coming from the Swainswick side, the footpath starts very near the parking coordinates. You will cross a second little bridge on your way if you come this way. Note the start of the footpath here is unusual; you may have done it before! Watch for GM and GDs, and please note the advice given at the start of the footpath.
If you come from Woolley, the footpath starts near the Woolley parking waypoint.
At the posted coordinates, you will find the little bridge. Find the Patent number which is a 6 digit number ABCDEF.
You will find the cache at N 51 24.DC5 W 002 21.AB5. Cache formula updated 23 Nov 2017. Continue along the path to the cache.
If you want to see the details of the patent this link will provide it. (Replace ABCDEF with the Patent number).
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:- www.littlebridgesseries.co.uk . If you would like to add to the series, please contact Stan via the Little Bridges website with your caching name, name of your Little Bridge and the GC code and he will give you a number for your bridge. 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.
