Opposite the Theodóra spring on the other side of the road you can find the starting point of a nature trail showcasing the natural beauties of the Káli basin. If you just look at it on a map you would think that these few square kilometres are not so exciting, but the real thing captivates you. Varied and colourful flora, thousands of insects and many small wild animals, flocks of sheep and the Kornyi lake - just to mention a few of the interesting things you can discover here. It is well worth joining the trail, even if it is only for a few stations!
