Perin grad
It is located downstream of Drinjača, ten kilometers from Šekovici, at the end of the village Kalabače. Near Perinje and Peringrad, the flow suddenly cuts deeper, forming a canyon stretching almost to the confluence with the Drina.
Is is believed that very important medieval roads to Srebrenica and Zvornik led along a part of Drinjača canyon, which was the reason for building a strong fortress at the entrance into the canyon.
Due to the inaccessibility of the terrain, a detailed exploration of the hot springs was not done but, anyway, the canyon, together with other natural features, is of a special significance for lovers of untouched nature (hikers, climbers, fishermen, rafters, hunters, etc.).
