Popradské pleso (csak engedéllyel / permit only)
Permit only: a glacial lake in the Mengusovská dolina in the High Tatras (Tatra National Park) at about 1,494 m, under the strictest level of nature protection; diving needs a permit from the environmental authority in Prešov. Divers who did it describe great diving with visibility up to 10 m. The lake used to be called Rybie pleso ('fish lake') as one of the few Tatra lakes with fish: brown trout breed naturally here and in the inflowing Ľadový potok.
depth: 0–17 m
