Get an earthworm's perspective of Sardina from Neptune's Caves
Below the surface, Sardinia is aerated with more than 300 caves. Some of the most famous are Neptune’s Caves, just a few kilometres off the coast of Alghero. These caverns were discovered by fishermen in the 18th century and they’re dripping with stalactites and spiked with stalagmites. There’s an underground lake here, too, which snakes through the cave floor for 120 metres.
