To re-iterate what Graham said, if it was by chance that you picked this area, you certainly are lucky! most people think that it is the best part of the island, and I think that you are going at one of the nicest times, as it is not too hot, and a bit less busy than in high season. This means that walking is a lot more pleasurable. We had hoped to get out in September, for our second visit of the year, but circumstances have conspired against us, so we will have to wait for next year!
Have you looked at the guide on this site for details of the area, it may give you ideas about what to do, and where to go, it can be found here:-
Good luck with the visit.
