A virtual cache at the Dean Burn Clapper Bridge, situated near the start of a track that leads up on to the open moor near Avon Dam Reservoir.
To log the cache, you need the logging password. To get that, find a four digit number engraved near the centre of the bridge. Multiply this by the number of lines of white text on the wooden plaque on the nearby gate. Your answer is the logging password.
The Dean Burn is a tributary of the River Dart that runs through Buckfastleigh and water from here was used in the woollen industry.
