The main reason behind this flying visit to Ischia is the sudden embarrassment to have realised that I've lived in Naples for 10 years and I've never been to this island!
Exactly, I never took advantage to go there back when it was right in front of me: I had to take a flight from London 😅
I bought the ferry tickets at Pozzuoli harbour straight from the Caremar ticket office. A passage to Casamicciola harbour, leaving at 10.15 am, returning at 5.30 pm, for two persons (me and mum, our small dog shipped free of charge), paid 35€ in total. The ferry made a stop at Procida and in about an hour landed to Ischia.
