You gotta be nuts

Thought this evening was a good day to go find a geocache I hadn't found before in Holyrood Park. It was a cold cloudy day so there wouldn't be lots of tourists. 

The cache requires you to scale down some cliffs so its best if its dry. It is labelled as a 4.5 * terrain, 4 * difficulty so it is quite challenging and there's not much of a clue. I spent 25 hunting around with no luck but I concluded I must be in the right place so went down again and looked under a rock I had previously not touched and there it was. Happy days.
