The Aquaworld Aquarium is one of the best places to see Crete's Fauna (wildlife) close up. The venue is in Hersonissos, about 30 minutes drive east of Heraklion. Aquaworld is a family run enterprise, friendly and well worth a visit. It makes great day out with the kids and a bit of education to go with it sees the exhibits close up. From the Heraklion direction, it is just off the main road, in town, behind Xalkiadakis large supermarket, located where you enter the built up central area of Hersonissos, on the right hand side of road.
