How to Get to Zannone #

Zannone is an uninhabited island in the Pontine archipelago (Lazio) and has no road access. It is reached only by boat - typically private boats or seasonal excursion/charter services from nearby islands (Ponza) or mainland ports (Anzio/Formia). If coming from Rome, drive to one of those ports and join a boat trip to Zannone; note that landing and access can be limited because the island is part of a protected area.

Tips for Visiting Zannone #

  • Book a day-trip boat from Ponza early in the season and reserve your spot in advance-Zannone is small and visitor landings are limited, so transport fills up quickly on summer days.
  • Stick to the marked trails and follow signage: Zannone is a protected reserve with archaeological ruins and fragile vegetation, so visitors should remain on paths and respect closures.
  • Plan for no facilities on the island-visit as a daytime excursion from Ponza, and ask your boat operator about permitted landing points and any reserve rules before disembarking.
