Just a five minute walk from Pile Gate (but a lot of steps!), heading away from the Old Town it was easy to find: there are some steps down on the left before reaching the tourist office, it is signed, and just keep to the shore. There are a lot of steps up to the summit of the outcrop where there is a bench with spectacular views of a small cove if you need to catch your breath. There are more steps up to the main entrance where there are great views back towards the Old Town at the top. You don't have to enter to get these views. Entrance is free if you have a ticket for the City Walls. Inside is an empty fortress but you can up another two levels again, from the very top the views over the old city walls and roofs is sensational. It was quite peaceful with only a handful of other visitors looking round.
