Laganas Bay & Marine Park · May–October

Swim With Turtles in Zakynthos, Greece

Zakynthos is the loggerhead turtle capital of the Mediterranean. Every summer, wild Caretta caretta turtles gather in Laganas Bay to feed and nest, and boat trips head out from the beaches to find them. The bay is a protected National Marine Park, so the focus here is respectful turtle spotting from the boat, with snorkeling in parts of the bay, rather than swimming right up to the turtles.

How Turtle Watching Works in Zakynthos

Laganas Bay is a protected nesting sanctuary, not an open-swim turtle spot. Loggerheads come here to lay eggs, so the marine park limits how close boats and swimmers can get, and responsible operators keep their distance and cut engines near turtles. Most trips are spotting-led: you watch the turtles from the boat or a glass-bottom hull, and snorkel in parts of the bay where you may see one in the water. If your goal is to swim right alongside turtles, a spot like the Maldives or Marsa Alam fits better. Come to Zakynthos to see wild loggerheads in their nesting grounds, and pick an operator that respects the park rules, keeps its distance and never chases the turtles.

How Much Does It Cost to See Turtles in Zakynthos?

Zakynthos turtle trips run from a short budget boat trip to a VIP speedboat or a snorkeling adventure. Prices depend on the boat, the length and whether snorkeling is included.

Snorkeling adventure
$49

A guided snorkel in Laganas Bay with gear, the most hands-on way to look for turtles in the water.

What affects the price?

Boat type

A shared boat or glass-bottom cruise is cheapest; a VIP speedboat with a smaller group costs more.

Spotting or snorkeling

Spotting trips watch from the boat; a snorkeling adventure gets you in the water for a higher price.

Trip length

Short Laganas Bay trips cost less than longer cruises that add Marathonisi and the Keri Caves.

Bottom line: For the classic Zakynthos experience, the Marathonisi and Keri Caves speedboat from $29 spots turtles and takes in Turtle Island. Add the snorkeling adventure if you want time in the water in the bay.

Sea Turtle Species & Best Months in Zakynthos, Greece

Species January–March April–June July–September October–December Likelihood
Loggerhead Turtle Offshore Arriving Common Departing Summer only
Zakynthos is all about the loggerhead turtle (Caretta caretta), a large, amber-shelled species that nests on the beaches of Laganas Bay. This is one of the Mediterranean's most important loggerhead rookeries, protected as a National Marine Park. The turtles are present from late spring through autumn and are almost never seen in winter, when they move to deeper water. Follow the park rules, keep your distance, and never touch a turtle or approach a nesting beach after dark.

Sea Turtle Behaviors to Watch For

Feeding in the Bay

Loggerheads feed on the seagrass and shellfish of shallow Laganas Bay, where boats spot them surfacing between dives.

Summer days
Surfacing to Breathe

A loggerhead rises to breathe every few minutes to an hour, the moment most turtles are spotted from the boat.

Throughout the trip
Nesting on the Beaches

Females haul out at night from June to August to nest on Laganas and Marathonisi beaches, which are closed or restricted after dark to protect them.

Jun–Aug, at night
Hatchlings to the Sea

Eggs hatch from August into October, and hatchlings make for the sea at night. They are protected and viewed only under guidance, never handled.

Aug–Oct

What to Bring (and What to Leave at Home)

✓ Bring

  • Reef-safe (oxybenzone-free) sunscreen
  • Swimsuit worn under your clothes
  • A hat, sunglasses and plenty of water
  • Towel and a change of clothes
  • Waterproof phone case or GoPro for boat shots

  • Your booking voucher (printed or phone)

✗ Leave at home
