The Fehértó has been a nature conservation area since 1966, and has been the part of the Körös-Maros National Park since 1997. The area is 5629 hectares. The alkali lake has been a nature conservation area under the Ramsar Treaty since 1979. In the end of winter thousands of wild geese and ducks gather into flocks to migrate to the north. Flocks of curlews, whimbrels and sandpipers have a rest on the wet grassy meadows at the lakeside.When the spring days start to warm, the avocet builds its nest near the water. In October and November the migration of cranes is a special event. Simultaneously with the cranes the wild geese also start migration to the north. In autumn very big flocks of birds spend weeks in the region. Tourists can visit the stocks of Hungarian grey cattle, racka and cigaja sheep owned by the Körös-Maros National Park at its Fehértó unit at Kardoskút, namely at the Sóstó establishment. These ancient domesticated animals have an outstanding value as they form a part of a Gene Bank for the purposes of the future animal husbandry.
