Update 26.07.2015 Following the alteration to the detail of this cache hide in 2014, which included a small change to the co-ords, there have been a lot of DNFs. As the series bonus is meant to be found, we thought a clarification would be good here, especially as it seems there has been a rearrangement of a key clue we had given previously. The cache is a camouflaged mino (halfway between a nano and a micro) and it is placed along the left hand side (as you approach from the pub end) wall of the tunnel. There's also a wee hint - a bit cryptic as usual!
The series can be done in any order, but is numbered from the recommended (free) parking area (coordinates given in SWAT1). There are other caches in the vicinity which you may want to consider finding if you haven’t already done so.
The route takes you mainly along footpaths (some could be muddy in winter) but there are a couple of short stretches of road where care should be taken with young children and/or dogs.
Don’t forget to take note of the Bonus Letter and value in each cache. These will be required to calculate the coordinates for the Bonus cache, SWAT14
