All tours depart from Agios Sostis pier in Laganas Bay — a 10-minute drive south of Zakynthos Town. Trips run daily from May to October, weather permitting. Departure times vary by tour.
The National Marine Park of Zakynthos protects the Caretta-caretta sea turtle nesting beaches along Laganas Bay. Our skippers operate within park regulations at all times, maintaining safe distances from turtles and nesting areas. Respect for the ecosystem is central to every tour we operate.
Guests should bring sunscreen, a hat, a towel, and water shoes for the swimming stops. Snorkelling masks are provided on Eros Cave departures. A light snack is available for purchase on board the Extended tour.
