It hosts more than 6 million of tourists every year who consume large quantities of water during their vacations. The study of the interdependence between water and tourism industry in Mediterranean islands with limited water resources is important for their prosperity. Their nexus in Crete has been investigated based on existing data regarding water consumption and the local tourism industry. The share of direct water use in tourism in the total water consumption in Crete has been estimated and compared with other tourism destinations. Tourism industry affects water resources in Crete while water is a basic resource in tourism industry. The share of direct water demand in tourism to total water consumption in the island, at 3.06%, is above the global average, at 0.6%. The high share of direct water demand in tourism industry to total water consumption in Crete, the expected future increase in tourists’ arrivals and the future reduction of water resources due to climate change indicates that improved management of water resources is necessary to avoid water shortages and water-related conflicts.
