A Zakynthos turtle spotting boat trip cruises Laganas Bay looking for loggerhead turtles at the surface. Compare the departure options in our tours in Greece pages before you book.
It covers the route, the loggerhead turtles, the marine park rules, Marathonisi and the Keri Caves, and the season.
What is a Zakynthos turtle spotting boat trip, and how does it work?
A Zakynthos turtle spotting boat trip is a sea cruise off southern Zakynthos. The boat searches Laganas Bay, a protected marine park area, for loggerhead turtles. It then stops for swims at Marathonisi and the Keri Caves.
The route is a loop that returns to its harbour. One operator page lists a first turtle search, then a swim at Marathonisi. Next come a second swim at the Keri Caves and a last turtle search on the way back. Two other pages follow the same order, so a Zakynthos turtle spotting boat trip has a clear shape.
Spotting is patient work. The boat moves slowly through the bay while everyone keeps a sharp look-out. A travel writer who made the trip says the boats in the bay stay in radio contact. They tell each other when they find a turtle.
Swim stops differ in length. A Zakynthos turtle spotting boat trip with one operator spends about 35 minutes at Marathonisi. Another operator plans about one hour there. On one boat, staff from Archelon, the Greek society that protects sea turtles, talk about turtle biology. The talk comes at the Keri Caves swim stop.
The routes also adapt. One operator says all its routes follow one plan but shift a little with timing, sea conditions and availability. Another page lists more Keri stops: Mizithres Rocks, Eros Cave and Pisines Beach, for swims and photos.
How long is a Zakynthos turtle spotting boat trip, and where does it start?
Operator pages put a Zakynthos turtle spotting boat trip between 2.5 hours and 5 hours in length. Three of those pages name the harbour of Agios Sostis as the place where guests board the boat.
Routes differ, and so do lengths. On one page, a Zakynthos turtle spotting boat trip is a 2.5-hour cruise from the port. Another page offers one version of 3 hours and one of 4 hours. A listing site shows three to five hours for one trip from Agios Sostis. A fourth operator states four to five hours, coach transfer included.
Start times differ too. One operator collects guests from about 8:30 in the morning and brings them back about 1:45 in the afternoon. Its afternoon tour picks up around noon and returns about 5:00. Exact times change with the resort. A second operator lists group departures at 9:00, 12:00 and 15:00.
A Zakynthos turtle spotting boat trip can also leave from Porto Roma. There, a rubber boat carried a travel writer’s group from the jetty to a catamaran. The group was back by 4:00 in the afternoon. The same writer says shorter trips run from Laganas. A listing site shows private boats leaving from Kavos Psarou.
Getting to the harbour differs as well. One page describes a coach from the resort. Another describes a train that carries guests straight to the port of Agios Sostis. The boat part of a Zakynthos turtle spotting boat trip then begins at that harbour.
Which turtles do you see on a Zakynthos turtle spotting boat trip?
The turtle on a Zakynthos turtle spotting boat trip is the loggerhead, Caretta caretta. The Greek sea turtle conservation society Archelon says three sea turtle species live regularly in the Mediterranean. Of those three, the loggerhead is the single one that nests on Greek beaches.
A loggerhead has a reddish-brown, heart-shaped shell, which green algae can cover. Wikipedia gives a fully grown loggerhead a shell length of around 90 centimetres and a weight of roughly 135 kilograms. A turtle must rise to take in air. So a Zakynthos turtle spotting boat trip scans for a head breaking the water.
Wikipedia says a loggerhead reaches sexual maturity within 17 to 33 years and lives for 47 to 67 years. It is omnivorous, feeding mainly on bottom-dwelling invertebrates. On open-sea migration it also eats jellyfish. Every turtle seen on a Zakynthos turtle spotting boat trip belongs to a long-lived species.
Nesting happens at night. One operator page says the females leave the sea in darkness to dig their nests. In summer, it says, the turtles swim in the park’s waters during the day. That daytime swimming is what a Zakynthos turtle spotting boat trip looks for.
Archelon adds that sea turtles have been seen sleeping under water for up to six hours. The average loggerhead dive is shorter, at 15 to 30 minutes, says Wikipedia.
Why do loggerhead turtles gather in Laganas Bay?
Loggerheads gather in Laganas Bay to nest on its six sandy beaches, which add up to 5.5 kilometres. Wikipedia says the biggest Mediterranean nesting area lies on Zakynthos. A Zakynthos turtle spotting boat trip sails across the bay beside that nesting ground.
Wikipedia says a female lays her eggs at, or close to, the beach of her own birth. The six beaches are Marathonisi, east Laganas, Kalamaki, Sekania, Dafni and Gerakas. Loggerheads were found breeding on these sands in the late nineteen-seventies. Archelon has recorded the nests systematically since the mid nineteen-eighties.
A Zakynthos turtle spotting boat trip taken in July or August falls inside the nesting season. Wikipedia says that season runs from late spring to August. A female comes back every 12 to 17 days to lay again. She lays four clutches on average, and a clutch holds about 112 eggs.
Sekania is a secluded beach 600 metres long. Archelon gives it about half of the nesting in the bay. Steep slopes behind it stop the shoreline from receding. Only scientific research is allowed there, so no passenger on a Zakynthos turtle spotting boat trip lands on it. Archelon’s count there adds up to 24,427 nests.
The eggs hatch in seven to ten weeks, depending on the temperature of the sand, says Archelon. Warmth also decides the sex. Wikipedia says eggs kept at 32 degrees Celsius become females and eggs kept at 28 degrees become males. Hatchlings dig up through the sand, normally after dark, and crawl toward the brighter horizon.
What are Marathonisi and the Keri Caves, and do they fit a Zakynthos turtle spotting boat trip?
Marathonisi is a small uninhabited island in Laganas Bay. The Keri Caves are sea caves under white cliffs in the south of Zakynthos. Operator pages list both as swim stops on a Zakynthos turtle spotting boat trip.
Its shape resembles a turtle, which gives Marathonisi the nickname Turtle Island. The island was inhabited until the Second World War. Now it is part of the marine park, and loggerheads lay eggs on its beach. Archelon says beach furniture and private equipment are not allowed there.
On a Zakynthos turtle spotting boat trip the island is a swim stop. One operator page says the boat anchors at the back, so the nesting area at the front stays undisturbed. That page gives about 35 minutes there. Another page gives about one hour and adds the Grand Cave.
The Keri Caves, the other stop on a Zakynthos turtle spotting boat trip, lie under tall limestone cliffs. A travel writer swam into a cave with a small beach inside, over large round white stones. Other pages add Mizithres Rocks, Eros Cave and Pisines Beach as swim and photo stops nearby.
Both stops fit a Zakynthos turtle spotting boat trip, but the order differs. Two pages start with a turtle search, then go to Marathonisi and Keri. One of them adds a last turtle look on the way back. A travel writer’s trip did the caves first and searched the bay afterwards.
What rules protect the turtles at the National Marine Park of Zakynthos?
Boats in Laganas Bay face a legal 6-knot speed limit. Archelon adds rules for watching a turtle: under 2 knots, 15 metres away, 10 minutes at the longest. A responsible Zakynthos turtle spotting boat trip follows them.
The park behind every Zakynthos turtle spotting boat trip covers 135 square kilometres in and around the bay. The water is split into zones A, B and C. Fishing is forbidden inside each zone. Boats cannot enter Zone A. In Zone B they go slowly and cannot anchor. In Zone C they go slowly and can anchor.
On a Zakynthos turtle spotting boat trip, Archelon’s list allows two boats at one turtle at a time. Other boats wait 45 metres away or further. The watching boat approaches from the side. Everyone on board stays silent.
Passengers avoid feeding or touching the turtles, because they are wild animals. Visitors enter the nesting beaches from seven in the morning until sunset. Digging in dry sand, lights at night and sunshades beyond five metres from the sea are banned. Sekania beach is closed to everyone except researchers with a permit.
Rules work only when crews obey them. A research project on the island says boats break the legal speed limit. It reports a very high risk of injury or death for resident turtles. A travel writer saw boats landing on a protected nesting beach. She advises an operator that respects the park rules.
That is the kind of crew behind a Zakynthos turtle spotting boat trip that leaves the turtles alone.
How does a glass-bottom boat compare with a speedboat on a Zakynthos turtle spotting boat trip?
A glass-bottom boat is the steadier ride on a Zakynthos turtle spotting boat trip. Its floor shows the sea below. A speedboat is smaller and goes furthest into the Keri Caves, but the ride is bumpier.
Aboard a Zakynthos turtle spotting boat trip with a glass floor, guests look straight down at the sea. One listing adds shaded seating and a rear sundeck. A boating site calls the steady hull the real gain, with the glass a bonus over shallow water. Another listing says the captain goes slowly or stops so guests can watch the turtles.
A speedboat carries fewer people. One operator page caps its semi-private speedboat at 10 guests, while its group boat takes up to 40. A second speedboat page lists small groups of 12 to 15 and cave entry. A boating site says small boats enter the caves, while big excursion boats stop at the mouth.
A fully transparent boat is a third option. One listing limits each cruise to eight guests and three hours, leaving from Limni Keri. It lists two swimming stops and a look at the cave arches from above and below the surface.
Shade and comfort settle the choice on a Zakynthos turtle spotting boat trip. One speedboat page lists shaded seating. The boating site calls speedboats the least shaded and unsuited to anyone prone to seasickness. A travel blogger praised a catamaran with a cabin and shade, and noted open boats with no shade.
Which season and sea conditions suit a Zakynthos turtle spotting boat trip?
One operator runs the Zakynthos turtle spotting boat trip daily between the midpoint of late spring and September’s end. Calm morning seas suit the trip well, since the afternoon breeze makes the return leg choppier. A rising swell can cancel a sailing.
A Zakynthos turtle spotting boat trip has a long season. Before the daily schedule, and again from October, the same operator sails on Tuesday, Wednesday, Friday and Sunday. A boating site puts the season at roughly April to late October, with very little in winter. Wikipedia gives the island a hot-summer Mediterranean climate: dry in summer, rainy in winter.
Mornings are calmer. The sea breeze builds through the afternoon and makes the return leg choppier, says the boating site. One operator page lists group departures at 9:00, 12:00 and 15:00, so a morning start is on offer. A travel blogger reports that trips are postponed when the wind is up and the sea is rough.
Keep the day flexible on a Zakynthos turtle spotting boat trip. One operator page asks guests to sail early in the stay, as the sea can turn unpredictable. Another warns guests of weather trouble one day ahead and then moves the date. A speedboat page adds that high swells can limit cave entry, so the captain picks other routes.
Archelon says sea turtles come into the bay to nest at the start of late spring. For a Zakynthos turtle spotting boat trip, the boating site notes that sightings are common in summer.
What else do travellers ask about a Zakynthos turtle spotting boat trip?
Does a Zakynthos turtle spotting boat trip always find a turtle?
No, a sighting is never certain. Turtles are wild animals, and a glass-bottom operator says nature is never 100% predictable. Its captains know the areas where turtles are spotted, but nature decides the rest.
A speedboat page says that without a turtle, guests still get the caves, two swim stops and a photo stop. One travel writer saw none on her Zakynthos turtle spotting boat trip, yet called it a great day out. She warns that guarantees on shorter Laganas trips tempt crews to harass the turtles.
What do I wear and bring on the boat?
A glass-bottom operator lists what to bring on a Zakynthos turtle spotting boat trip. It names a hat, sunglasses, sunscreen, a towel and swimwear, plus water and a phone or camera. A speedboat page adds a light cover-up or rash guard. It also asks for a waterproof phone case and biodegradable sunscreen only.
Bring your own snorkel gear, since one operator supplies none for hygiene and safety reasons. That boat welcomes a packed lunch and has a small snack bar with coffee, chips, ice creams and sandwiches. Toilets are on board that boat, too.
Can children, guests who cannot swim and people prone to seasickness join a Zakynthos turtle spotting boat trip?
Families join in. A glass-bottom operator calls its calm cruise suitable for children, couples and groups. A speedboat page welcomes children of all ages with an adult and offers infant life jackets on request. Another operator adds an optional pirate game for children.
The speedboat page says life jackets are mandatory in the water. Guests who cannot swim can stay on deck, or float beside the boat with the crew watching. Snorkelling is optional on a Zakynthos turtle spotting boat trip. The page lists seasickness tablets for anyone prone to it and warns of boat motion.
Is hotel pick-up included, and when does a Zakynthos turtle spotting boat trip start?
Pick-up for a Zakynthos turtle spotting boat trip depends on the operator. A speedboat page lists pick-ups from Laganas, Kalamaki, Tsilivi, Argassi, Alykes and Zakynthos Town. A 20-minute transfer to Agios Sostis follows. A coach operator covers nearly all resorts, so check that yours is on its list.
The speedboat page confirms the exact pick-up time by WhatsApp or email 24 hours before. It collects guests from the nearest road point if the hotel sits in a pedestrian zone. A glass-bottom operator sends the meeting point after booking and asks guests to come 15 to 20 minutes before departure.
What happens on a Zakynthos turtle spotting boat trip when the sea is rough?
The route adjusts to the weather. A speedboat page says its itinerary changes for weather or park rules. A glass-bottom operator lists Eros Cave and Piscines as bonus stops that depend on the weather. A guest review on the speedboat page says weather shortened one stop, but the crew adapted.
A coach operator calls sea conditions unpredictable at times. On a Zakynthos turtle spotting boat trip, it says it tells guests openly when changes are needed. It offers a new date or an alternative plan. The speedboat page adds that life jackets are mandatory during the cave segments.
