The Fox Cave is located in the Karajimiškis Landscape Reserve. The diameter of the cave on the ground is 16 x 17.2 m. Its depth is about 7.4 m. This sinkhole is distinguished by the fact that it contains a lot of chaotically welded dolomite with gypsum interlayers. The cave is dry all the time. In spring, when the accumulated snow melts, the water does not freeze.
