Spent half day here in late September, the history of the castle and all who inhabited it down through the ages makes it so interesting to visit. We queued for approx 15 min to get in, €12 entrance and started the gentle climb to the top. Coffee shop half way up with beautiful views and restaurant at the top (overlooking Naples bay and as far as the eye can see) that is ideal for lunch and reasonably priced. Do not miss out on the Putridadium Cemetery of the Poor Clare nuns and the display of the torture equipment used in the day. Allow 3 hours and you will not be rushing, loads of gorgeous photo opportunities.

An amazing old castle. One of the best castle experiences we had in Italy. Very small entry fee, well worth it for a self guided tour. The massive structure stands on a volcanic rocky islet that connects to the larger island of Ischia by a causeway. Originally the castle was built by Hiero I of Syracuse in 474 BC. If it’s a hot day take your bathers and have a swim in the water near the causeway.

Well worth the ticket and the hike up. It was busy but you were able to feel alone with the experience. I tried both cafes since the day was chilly. Excellent staff! It was easy to get around and enjoy the nature as well as see the remains of the convent, churches and the prison. Excellent adventure. Either walk from town or better to take the mini bus to Ischia Ponte.
