It should be cloudy today. So we are heading for Tre Porcellini. From Finale Ligure drive towards Calice Ligure. After you cross below the Autostrada take the second street to the right. It's signed with Rocca di Perti. Be aware that because of the remote location of the parking lot, it tend to be visited by car thiefs.
There is a sign to get up to Tre Porcellini, but this path is steep and sweaty. If you follow the road, you can easily travers to the crag.
