"Vējiņi" underground lakes

The Ezerala Cave consists of a unique cave system with an underground spring and two underground lakes. Its total length is 48 m. These lakes are the only underground lakes discovered in the Baltics so far. The biggest lake’s surface area is 30 m2, length 14 m, depth up to 2 m. The area of the smallest lake is 15 m2, length 6 m, depth around 5 m. Above the large underground hollows there is only a 6m thick but unreliable cover of Quarternary sandstone deposits, therefore only guided sightseeing of the underground lakes is allowed.
