The tour over the Cave di Caolino is absolutely amazing and worth a visit. The Cave di Caolino is a gorge with a variety of rocks. The yellow character comes from the sulfur-infested soil. Next to the path, the layers of rock change up in the most amazing colors. Glittering crystals are rinsed out in rainfall. Once at the bottom, you go a sometimes well-grown trail always in about 100 meters above the sea for about 3 km along. Dozens of Gekos run into each other. It is essential to wear long trousers because sometimes thorny plants stand in the way. On clear days, from the starting point you can see the Etna in Sicily in the distance.
