Lake Mir is located in the Telašćica Nature Park on Dugi Otok, more precisely, in its western part.
This lake is specific because of its closeness to the sea and amazing views and peace. It was formed in the last ice age when the karst depression was filled with sea when the ice had melted.

Underground canals are a characteristic of the karst area and through them the lake receives water from the sea. The lake is saltier than the sea due to water evaporation and the closedness and isolation of the lake itself.
The underground channels are mostly located on the northern side of the lake and they are most easily noticed at high tide. The water level in the lake does not change drastically because the cracks through which water gets into it are very small.
During stormy south winds, the sea in the southeastern part of the lake overflows into the lake.
The lake is 900 meters long and 300 meters wide. In the shallower parts of the lake, the bottom is rocky, and in the southeastern part of the lake it is covered with fang – healing mud.
The greatest depth of the lake is 6 meters and it is generally considered a shallow lake. The shore of the lake is rocky with a lot and the habitat of the endemic species is the dubrovačka zečina. In the northwestern part the coast is sandy.
Due to its shallowness, the lake heats up and cools down quickly. The temperature amplitude of the water ranges up to 33 ° C in summer and up to 5 ° C in winter. Due to its extreme salinity and large differences in temperature in summer and winter, the lake is biologically quite poor.

A few donkeys can be seen around the lake, and the cliff on the outside of the cliff is where the gray falcon nests. If you decide to swim on one of the quiet beaches of this lake, at the bottom you will notice sea bass, various species of shellfish, single crabs, ten-legged crabs and many other organisms.
Lake Mir is a habitat of an endemic eel species called “bižat” or “man”.
