Part of the B&T Canal Series.
Walking towards Taunton, as you get to Brige 20, you are in the right area. Have a good look and inspection of your surroundings as this hide is subtle. You are looking for a nano cache - tweezers required to get the log book out.
PLEASE DO NOT MOVE THE SWING BRIDGE BY THIS CACHE - you do not need to move the bridge to locate the cache.
Happy caching!
