Istállós-kő is a mountain in Hungary. With a height of 958.1 metres above sea level, it is the second highest mountain of the Bükk mountains and the sixth highest of Hungary. Before 2014 it was considered to be the highest point of the area, but according to recent surveys Szilvási-kő is 960.715 metres meters high. It is easily accessible from Szilvásvárad on a few hundred meters long tourist path, which leads to a cave in the mountain.
