The Cartoromana belvedere overlooks the sprawling 'Termale Eden' spa. That popular thermal spa was in the process of preparing for opening in the next few weeks. Those islets trace the edges of Ischia's own submerged ruin, the 'Villa Romana'. Snorkelers love to explore those ruins. As we traipsed across that SE corner of the isle, we joined another hiker. She was lovely young Veronique, a Belgian archaeologist who worked in Holland. She was also very knowledgeable about Euro-travel in general.
