The Vasilashki Lakes (Bulgarian: Василашки езера) are situated in Pirin, Bulgaria in a large cirque between the Todorka and Vasilashki Chukar peaks.
The cirque is opened to the east, where it faces the Demyanitsa river in which the water of the lakes pour.
The cirque is amphitheatric and in fact consists of several smaller cirques situated in a fan-shape way above the main one, in which the two largest lakes are located.
The lakes are 10 including the two Todorini, with a total surface area of 160 decares.
Their name derives from the legent for Vasil, the beloved one of Todorka, who plunged into the Fish Vasilashko lake when she broke his heart.
