The Seven Lakes are a tourist attraction in Bulgaria because of its natural environment. The lakes are located one above the other and are connected by small streams, which form tiny waterfalls and cascades. Tourist accommodation in the lakes' vicinity include a chalet on the northeastern shore of The Fish Lake, at an elevation of 2,196 m.[citation needed] The most common time to visit the lakes is summer, in July and August, when temperature is above 10 degrees Celsius and the risk of sudden storms is lower.[citation needed] During the rest of the year the weather can be severe.[citation needed] The lakes usually freeze during October, and do not melt before June.
