CRETAquarium Thalassokosmos
CRETAquarium, also called Thalassokosmos, is the public aquarium at Gournes on the north coast of Crete, about 16 km east of Heraklion and under 10 km from Heraklion airport. CRETAquarium holds Mediterranean marine species in walk-through tanks, and most visitors spend two to three hours inside. The building sits less than 1 km from the centre of Gournes village, directly off the coastal national road.
This is the closest large indoor attraction to the Heraklion resort strip, which makes it the standard answer to a wet or windy day on that coast. Dinosauria Park stands beside it, so the two fill a half day together without moving the car.
What you see at CRETAquarium
CRETAquarium shows the marine life of the Mediterranean rather than a global collection. The route runs through walk-through tanks, and the species on display are the ones that live in the sea immediately outside, which is what separates it from an aquarium built around tropical exhibits.
Allow two to three hours for the full circuit. Current exhibits, opening hours and ticket prices change by season, and the operator publishes them on the official site at cretaquarium.gr, which is worth checking on the morning you go.
Where CRETAquarium is
CRETAquarium stands at Gournes, on the stretch of coast between Kokkini Hani and Kato Gouves. Heraklion lies about 16 km west and Hersonissos about 10 km east, and the aquarium sits on the seaward side of the national road that links them, signposted from both directions.
The airport is the closest of any major attraction on this coast, under 10 km west, so the aquarium works as a first or last stop on a Crete trip when a flight leaves too late to justify a full day elsewhere. Buses along the coastal route serve Gournes through the day.
Combining CRETAquarium with the rest of Gournes
Three things sit within a kilometre of the entrance, listed below from nearest to furthest.
- Visit Dinosauria Park, 800 m away, which pairs naturally with the aquarium for anyone travelling with children.
- Swim at Gournes beach, which runs below the resort strip a short walk north and forms part of the 23 km of near-continuous beachfront between Vathianos Kambos and Malia.
- Spend the rest of the day in Gournes itself, 900 m away, or walk the Agia Anastasia Gorge, which starts inland at Kenourgio Horio and finishes at the village.
Where to eat near CRETAquarium
Eating options cluster along the Gournes seafront within about 1.5 km, and the range covers Cretan taverna cooking, grills and bakery food rather than anything formal.

- Sousami Cretan Bakery sells bread, pies and pastries 800 m away.

Frequently asked questions
Where is CRETAquarium?
CRETAquarium is at Gournes, about 16 km east of Heraklion on the north coast of Crete, on the seaward side of the coastal national road between Kokkini Hani and Kato Gouves.
How long do you need at CRETAquarium?
Allow two to three hours for the full route. Adding Dinosauria Park next door turns the visit into a comfortable half day.
How far is CRETAquarium from Heraklion airport?
Under 10 km west, which makes it the closest attraction of its size to the terminal and a practical stop on an arrival or departure day.
What is in CRETAquarium?
Mediterranean marine species, shown in walk-through tanks. The collection covers the sea around Crete rather than tropical species, so the fish on display are the ones living off the coast outside.
Is CRETAquarium worth it on a rainy day?
It is the main indoor option on this stretch of coast. The aquarium and Dinosauria Park beside it are both under cover, and together they fill the part of a day that the beach cannot.
Where do you check opening hours and tickets?
On the operator’s own site, cretaquarium.gr. Hours and prices move with the season, so the published timetable there is the one to trust on the day.
