The hike into the cache area is across a man-made causeway to a mini- suspension bridge. The bridge was built in the 1930s by a North Berwick company that now makes seats for giant stadiums. Legend has it that, in the 1940's, a group of Girl Scouts created the nickname for this bridge because the bridge wiggles when you walk over it.
The cache is a micro magnetic container. There is no need to go underneath the bridge.
For a scenic walk and another cache, continue over the bridge and follow the path through Steedman Woods.
