Audio Guide of Marathonisi Island

Marathonisi is an uninhabited island with no official opening hours, as it is a protected natural area. It is mainly reached by boat from the port of Zakynthos or directly by kayak from Porto Limnionas Beach; I recommend booking a local excursion to visit during the day, ideally between 10:00 a.m. and 4:00 p.m.

There is no entrance fee to access the island itself, since it is a public natural area. However, boat or kayak transport has a cost, usually ranging from 25 to 50 euros per person depending on the provider. If you plan to snorkel, rent your equipment at the port of Zakynthos before setting off.

It is recommended to plan a visit of at least 2 to 3 hours to explore the cave, swim in the crystal-clear waters, and snorkel on the nearby reefs. If you enjoy hiking, you can add an extra hour to walk to the top of the island. Boat excursions usually last 4 to 5 hours in total, including travel time.

Marathonisi, also known as Turtle Island, is vital for the conservation of the loggerhead sea turtle (Caretta caretta) and the European shag, serving as a nesting area. Culturally, it was used by pirates in the past because of its hidden caves, although today its value is purely ecological within Zakynthos National Marine Park.

The best time is between May and October, especially June or September, to avoid the peak tourist season in July and August. I recommend visiting in the morning (9:00 a.m. - 12:00 p.m.) to enjoy calmer waters and fewer people. If you go during turtle nesting season (August-October), always follow the minimum distance rule of 5 meters so as not to disturb the wildlife.

Unfortunately, it is not accessible for people with reduced mobility because of its rocky terrain, lack of infrastructure, and access only by small boat or kayak. Boarding at ports such as Zakynthos can be difficult without assistance. For inclusive options, consult local tour operators on Zakynthos for adapted excursions.

From Zakynthos, you can visit the famous Navagio Beach and Porto Limnionas, or the white caves of Keri. In the northern area of Zakynthos, near Argassi, you will find Tsilivi Beach and Keri Lagoon. Use the official Zakynthos website for more information about combined tours.

Bring sunscreen, water, and food, since there are no services on the island; wear non-slip footwear for the rocks and avoid touching the limestone formations in the cave. For snorkeling, bring your own equipment or rent sustainable gear, and never touch or feed the turtles; more tips at Visit Zakynthos.
