Lysaya, mountain in Stavropol Krai, Russia

Mount Lysaya (Boralyk) is an asymmetrical dome-shaped remnant of a Paleovolcanic mountain in the eastern part of Pyatigorye, rising to 739 m. Its northern slope is steep (15–18°) while the southern slope is gentler. The mountain is composed of Upper Cretaceous and Paleogene limestones, marls and clay shales, with travertines on the eastern slope.

Lysaya is a relict magmatic paleovolcano made of Upper Cretaceous and Paleogene limestones, marls and clay shales, with an intrusive body of beshtaunites exposed by boreholes at a depth of 600 m. On 15 September 1961, by decision No. 676 of the Stavropol Krai authorities, it was declared a regional complex landscape natural monument.

The mountain is a favored destination for local hikers and nature enthusiasts who regularly visit for day trips. People come here to enjoy views and spend time outdoors in the Caucasus region.

Visitors can reach the mountain via established hiking trails from nearby settlements that are accessible year-round. Spring and autumn provide the most comfortable weather for day visits to the area.

The name Lysaya means "bald" in Russian, but the mountain also bears the Turkic name Baralyk. Its eastern slope contains travertine deposits, and boreholes at a depth of 600 metres revealed an intrusive body of beshtaunite.
