The establishment of the Great Milic Nature Park is connected to Felső-Hegyköz: The idea of the nature park originates from the local governments of the settlements (Hollóháza, Füzér, Pusztafalu) situated on the southern side of the Great Milic mountain group and at its hilly forefront. The Slovakian villages on the northern side of the Milic (Szalánc (Slanec), Szalánchuta (Slanská Huta), Eszkáros (Skároš), Újszállás (Novỳ Salaš)) joined this initiative and they were followed by Füzérkomlós and Kéked from the Hungarian side.
