3 Hours Marathonissi Island Tour, Keri Caves and Turtles Spotting

Itinerary

60 min

Enchanting Island of Marathonisi islet Stop for Swimming at beautiful Sandy Beach. Marathonissi is a small private island in the turtles’ bay close to Limni Kerì’s beach. Until the second world war the island was lived, today it has neither inhabitants nor buildings. It is now one of the areas where the CARETTA CARETTA turtles go to breed.

40 min

First Stop will be at Keri Caves - Amazing place First Stop for Swimming Kerì Caves, accessible only by sea with private boats or our excursions, develop along the promontory of Marathia Cape, in the South-West area of the island. Along the coast there are many caves which entrances scarcely suffice to get in swimming, others are broad enough to enter directly with a boat. It is very easy to reach the caves that are surmounted by cliffs where the sea is very deep and as such reachable.

45 min

Turtle Spotting: Starting with Turtles Spotting just out in the Laganas Bay The Caretta Caretta Turtle is a specimen still living in the Mediterranean and it is possible to meet it there since it spawns along the beaches of the Laganas Gulf. They can have considerable dimensions (the largest weights 140 kg. and measures circa 120 cm whereas the smallest measures 80 cm.) but, in spite of this, they are very fast. Thanks to the big anterior and the stiff posterior fins they can reach 30km/hour and so protect themselves from possible dangers.

Just the very basics...

There was nothing special to see. Marathonisi beach was just an ordinary beach. Maybe, because of the very windy weather we could not see the alleged crystal clear waters. And if you want to see more interesting sea caves better prefer the ones at the north of the island, near the shipwreck beach.

Definitely worth it

The collection went a bit chaotic, about 60/80 people gathered at the boat which could hold 23, so people started to push a bit because they were afraid of missing the boat. The majority turned out to be for two other boats. The trip was fun, the captain was a very suitable guy, super relaxed and helpful. The tour was exactly as described.

It was ok

Arrival was chaos. Huge queue, panics that there wasn't enough space on the boat. Another one thankfully arrived. Once on the boat, we were taken to the 1st stop. We were informed we would be there for 1.5 hours, which on the face of it was good, however in the blistering August heat with no shade, it wasn't ideal with young children. We then spent the last 30 mins going to see some caves a 5 minute dip off the boat and 5 mins to see the sea turtle. Both guides were great although the company's arrangements were chaotic. It was more like a ferry service We would recommend it but with the 3 hours fairly spaces out

Beautiful trip

It's nice that only 25 people go on the boat, that's what we pay close attention to. El Capitano, with his great Dagobert Duck swimsuit, had a smile on his face the whole ride. With great pleasure he showed us all the beautiful places. We had a great afternoon!

Not to be missed!

Fantastic excursion, suitable for children, few people (less than 20), optimal glass bottom for seeing the turtles well
