On the south side, by the sea, Cat Mountain rests on a cliff Swan's Wing (95 m) - a limestone rock that resembles an open wing of this bird. Since 1947, the Rock of the Swan's Wing along with the mountain of the Cat is a complex natural monument, which has the status of “state importance” since 1984. In addition to the Swan's Wing cliff, there are other original limestone rocks near the Cat's mountain: the Diva rock (45 m) and nearby - fragments of Monk rock destroyed by storm, a little further - Panea rock (85 m). These cliffs create a unique landscape of the entire coast. In ancient times, all of them, having broken away from the Ai-Petri massif, slipped into the sea.
