This is a Little Bridges dash'n cache. It involves going down a lot of steps, before following the pathway adjacent to the stream, which leads to the bridge.
There is roadside parking nearby.
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, Damian from Winter Foxes has created and updates a list of cachers who has found 10 or more little bridges and can be found here, if you would like to add to the series, please contact Stan on stanthews@aol.com 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 # xx then name” including spaces so it will get picked up and added to Damian’s list.
