Lacul Sfânta Ana

Lake Saint Anne is the only volcanic lake in Romania, formed in the crater of an ancient volcano in the Ciomatu massif, in the Szekler land. Its water comes almost exclusively from precipitation, making it extremely pure with very low mineral content, which gives it its characteristic transparency and a colour that shifts from blue to green depending on the light. The nearly circular shape of the lake, framed by the dense beech and spruce forest covering the crater slopes, offers a landscape of rare symmetry, especially spectacular in autumn.

Nearby lies the Mohos peat bog, a protected marsh with rare plant species, which makes the area a valuable destination for nature lovers. The site is also tied to folk legends that explain its name. Practical note: access is by forest road or marked trails; for swimming, check the rules in force, as this is a protected natural area that must be treated with care.
