The cave is impressive, we pass through different rooms before arriving in the cathedral, passing over an underground river. You really feel like you're exploring the depths of the earth. Once outside, it's good to find the sun and the colors of life! Don’t leave without buying some cheese matured in the caves, it’s perfect for an aperitif!
