This mound, declared together with the adjacent area and as a nature reserve, is a place of occurrence of rare flora and healing mineral springs springing in several places. One of these springs is adapted to take water by visitors, another, perhaps the most interesting, springs in the form of a geyser and represents one of the two geysers in Slovakia (next to the cold geyser in Herľany). Small travertine craters can also be found on Siva Brada, from which water does not spring up, but carbon dioxide escapes from them, which can kill even a smaller animal in the event of a massive inhalation. Gas leaks are paid for mainly by birds, whose dead bodies can be seen here and there in the locality.
At the top of Siva Brady, the romantic Baroque Chapel of St. The cross, which is a traditional destination for pilgrims, and which makes the site significantly more attractive and interesting for lovers of cultural monuments.
