An encounter with life underground
In the tunnels beneath Kranj’s old town, Tular researchers introduce the olm through aquariums, films and displays. Discover how this animal lives in darkness and why protecting groundwater matters to wildlife and people.
A visit that supports conservation
The olms here were rescued after floods washed them to the surface. Researchers monitor how visitors affect the animals and use those observations to improve their care. Admission income supports olm research and conservation.
