We had a lot of troubles to finde the trail. It always disapears suddenly. So from the planned mountain-running tour there got a thorn-hiking tour, of corse with open shorts :)
But nice wheater and clear views. The view is great from here!
We summited Rocca Busambra from Alpe Cucco and the easy east ridge during our 2005 Sicily stay; unfortunately we had no optimal weather because whenever it gets a little bit humid over Sicily Rocca Busambra acts as a cloud catcher. The huge advantage: it does not get too hot :-)
Great hike on one of my Sicilian favorites.
