In the beginning of April, thanks to Szabolcs Leél-Őssy, a little group had the opportunity to see the Mátyás-hegy cave on a guided tour. Szabolcs Leél-Őssy is a graduate geologist, associate professor, caveman, climber, specialist writer and a candidate to earth sciences, so the children received information and learned about this world from the most competent person possible. Though the first few meters proved that this would not be a light stroll on a paved and lit road, everyone agreed that they took part in one of the most enjoyable programs of the year. We had to descend from high to low on countless ladders, we crawled in mud and darkness, but it was worth it. Furthermore, I believe none of us have ever been as muddy on the tram before as we were on our way home. The cave tour was very exhausting, but we agreed that we would go back there or to other caves in the future.
