With our free shuttle service you can easily reach the center of Sorrento and then by 10 mins walk reach the Port for the hydrofoil. From Sorrento Port only leaves the hydrofoils to Ischia (that run less frequently than those one to Capri).
For Procida you've to reach Napoli Port first.
We suggest to visit both Islands with a great Minicruise on the ship "Marine Club" that leaves directly by the Port in Sorrento. Tickets are sold at the Port or in the main travel agency.
Ischia: it is the largest of the island in the bay of Naples, the "green island" for its abundance of pine-tree forest. Its volcanic nature makes it unique in the world for the great variety of thermal and radioactive springs, practically found every where on its territory.
Ischia is divided into six commune districts and is the major tourist port for its importance; The "Ponte" area is distinguished by the rock on which the Aragonese Castle was built.
Procida: It is the smallest of the three islands of the bay of Naples, and surely the most genuine.
It is the island where it is still possible to admire the typical classical architecture of Mediterranean pink and white washed houses inhabited by the fishermen still living on the island.
Procida is almost totally flat and on the only headland lies a tufa building used as a penitentiary in the past.
