Since we want to keep our planet clean and make sure that the future generations will have a bright future, we are doing our best to take as many sustainable steps as possible within the shortest possible time. By introducing sustainable solutions into our stories, we are gradually changing the habits of individuals and raising awareness of the importance of preserving a clean environment and the underground world, which is home to numerous subterranean animals and also the source of our drinking water.

Think Deeper

The karst surface is highly permeable, which makes reducing the amount of traffic in the Karst all the more important. There is another world under the Earth’s surface. Everything that gets polluted on the surface ends up underground. By using sustainable public transport in the area of the karst fields and the caves underneath, you contribute to the preservation of a clean environment and our drinking water.

Our mission is to also protect the world under the Earth’s surface and thus preserve the subterranean natural beauties, so all the coming generations will get to enjoy them in the future. The Postojna Cave Park boasts some of the finest natural wonders and is happy to welcome any curious visitor who wants to see the beauties of nature in person. Aiming to preserve the pristine nature, we do our best to act as sustainably as possible at all levels of our work and gradually change the habits of both our employees and visitors. One of the main steps is to introduce sustainable mobilityin the Postojna Cave Park and beyond.

Cars emit exhaust gases into the atmosphere, and large amounts of toxic substances onto the surface and into the underground world. These toxicants include road dirt, chemicals in windscreen cleaners, condensation with numerous toxic impurities, oil, lubricants and tyre microplastics. On rainy days, all the road dirt seeps through the permeable karst surface into the underground world and the groundwater.

Side by Side towards Changes

Excessive use of individual means of transport results in unendurable and unconscious destruction of the underground world, which is the main source of our drinking water and home to many animal species. Postojna Cave is considered the cradle of speleology and a habitat for more than 150 cave-dwelling animal species, including the world-famous phenomenon – the olms also known as the “baby dragons”, which are endemic to our underground world and are a symbol of clean water. This is a step in the right direction that’s in the hands of us, humans. The more awareness there is at the individual level, the bigger the community united by the desire to preserve the planet forever young and thus ensure a better future for the next generations.

For this reason we are extremely proud of our ongoing Protect Proteus Project, which helps us fulfil the mission entrusted to us by nature with the hatching of olms (the proteus) – to ensure a healthy habitat for olms. As part of the project, we are developing laboratories for the development of this animal species, raising awareness of the importance of groundwater and drinking water, and keeping the planet forever young. We encourage everyone to become a Superhero by adopting sustainable approaches and responsible behaviour.

Sustainable Travel

An important step towards making our company operations and our community sustainable is the newly established SHUTTLE BUS, which runs on the route Postojna Railway Station – Postojna Cave – Predjama Castle and back. The bus is part of the international project Predjama Sustainable, which promotes sustainable mobility and contributes to mitigating climate change. We also strongly encourage the use of other public transport options that bring visitors to Postojna.
