After a tough night on the horse farm we decided to skip the horse and cart ride and meet up with Martin for a canoe ride on the disappearing lake.

As we canoed and walked the lake Martin covered the geology, biodiversity, politics, myths and lots more about the lake. A great guide really, interested in so many different aspects affecting the lake.

Pizza for lunch to the sound of The Pretenders and ACDC. Very kind waiter.

To Postojna cave system for an underground train ride and guided walking tour. Amazing - I thought Jenolan Caves were impressive but this cave system is enormous.

Karst, karst and more karst - stalactites, stalagmites, columns, swallow holes, lakes ending up In the Black Sea.
