We have experienced this service on a day in early May with uncertain weather (later improved): this has resulted in a limited number of participants (ten), which likely affects the good quality of the experience.
We refer specifically to the service that provides, for 25 euro each, a circuit of five hours (11am-4pm) around the islands of Ponza and Palmarola, with stops for swimming. In my opinion it's an excellent value for money, for the sublime natural spectacle that is offered, and because a freshly cooked pasta dish, water, wine and coffee are included in the price (in high season the period is 11am-5:30pm, probably for a higher price).
The boat used is essential, but modern and efficient.
You should turn to the headquarters of the boatmen cooperative within 10:30 am on the chosen day. Bring sunscreen!
I don't hesitate to affirm that the circumnavigation of the two islands, because of their scenic volcanic nature, is one of the greatest natural wonders that you can enjoy throughout Italy. Absolutely recommendable, it alone is worth the journey from the mainland.
