Zakynthos is home to one of the Mediterranean's most important loggerhead sea turtle (Caretta caretta) nesting grounds at Laganas Bay. The National Marine Park of Zakynthos protects this vital habitat, and visitors can join guided night tours to observe turtles nesting on the beach.
Laganas Bay on the southern coast of Zakynthos in the Ionian Islands of Greece contains one of the largest and most important loggerhead sea turtle (Caretta caretta) nesting grounds in the Mediterranean. The National Marine Park of Zakynthos was established in 1999 specifically to protect this habitat, encompassing 135 square kilometres of marine and terrestrial zones covering Laganas Bay and portions of the surrounding coast. The park designates three levels of protection: core zones where all human activity is restricted during nesting season, buffer zones where controlled access applies, and peripheral zones where tourism operates under guidelines.
Loggerhead turtles begin arriving at Laganas Bay from late May onward, with peak nesting activity occurring in June and July. Female turtles emerge from the sea at night — primarily between 9 PM and midnight — to excavate nest chambers in the sand and deposit clutches of 80 to 120 eggs. The eggs incubate for approximately 55 days, and hatchlings emerge from late July through September, making their instinctive dash toward the sea guided by moonlight. Both nesting and hatching are best observed on licensed guided tours organized through the marine park authorities or authorized operators in Laganas village.
The guided tours are conducted under strict protocols: no torches or flashlights on the beach, no photography with flash, and movement restricted to designated paths supervised by licensed guides. These restrictions are essential as artificial light disorients nesting females and hatchlings alike. Groups are typically small — around 10 to 15 participants — and the waiting time before turtle activity is detected can be significant.
Beyond the turtle experience, Laganas Bay has good beaches and a range of accommodation and restaurants in Laganas village. The marine park information centre in Zakynthos Town provides background on conservation research and the ongoing protection challenges posed by boat traffic and beachside development.

When to visit
Late June through July offers the best probability of observing nesting females, while August and September provide the chance to witness hatchling emergence. Tours operate nightly; booking at least two to three days in advance is essential in peak season.
Accessibility
The nesting beaches are accessed on foot along sandy terrain in darkness, making the tours unsuitable for wheelchair users. The marine park information centre in Zakynthos Town is accessible and provides detailed conservation context for visitors who cannot participate in the beach tours.
Frequently asked questions
How do visitors join a guided turtle nesting tour?
Licensed guided tours are organized by the National Marine Park of Zakynthos and authorized operators in Laganas village. Tours run nightly from June through August, departing around 9 PM. Advance booking is strongly recommended as group sizes are strictly limited.
Is it guaranteed to see turtles on a guided tour?
Sightings are not guaranteed, as turtle activity depends on natural behavioral cycles. However, licensed guides monitor the beach throughout the evening and move groups to where activity is occurring. The majority of tours during peak season in June and July result in an observation.
Can visitors access the nesting beaches independently at night?
Core zone beaches are closed to unguided access during nesting season (June–September). Entering these areas without a licensed guide is illegal under marine park regulations and can result in significant fines.
Is photography allowed during the tours?
No flash photography is permitted on the nesting beaches at any time during nesting season. Completely dark photography without flash may be permitted at the guide's discretion. Protecting the turtles from light disturbance is the overriding priority.
