This is a walk of 2 hours plus, starting from the recommended parking. It is on offroad tracks and paths and takes you out to the light house and back again via the actual cache.
Ideally you can go to the lighthouse terrace, find some clues and calculate the final coordinates. The final part of the walk to the lighthouse has restrictions on almost all types of transport although motor bikes, off road vehicles and cycles can get part of the way. Please include in your log whether you walked all the way or took an easier method! If the terrace is closed the clues can be answered by going to the end of the promontory and looking back at the lighthouse - there are suggested coordinates for viewing the north side of the lighthouse.
The coordinates are for the north side of the lighthouse - if access to the terrace is available the clues should be easy to answer otherwise it is a little harder. To find the cache - take the road back (approximately South West to begin with), then turn off up another road and the direction should lead you to a path and an area where the cache will be found.
The number of the letters on the two sides of the tower you can see from the terrace (or from any viewpoint) = AB
The total number of doors and windows with blue shutters on the north side of the lighthouse = C
The number of sides of the tower = D (D is more than 3 but less than 8)
The coordinates for the final cache are:
N 42 34.(C+D)(B-C-D-1)A E 008 43.(C-A)BA
