This is a part of Latvia in which various manifestations related to layers of earth made up of water-soluble lime can be found. The most unusual elements here are Lake Vecezers and Lake Linezers. The water of the latter lake has flowed underground several times over the last few decades, with the remaining lake hole as much as nine metres deep. No one can fully explain how this happens. A tourist trail encircles Lake Linezers.
