Neptune’s Grotto
This geological treasure is easily accessible by boat from the harbour of Alghero but if you prefer the exercise, you can brave the 656 steps of the Escala del Cabirol stairway from the top of Capo Caccia, 110 metres along the cliffside and down to the cave entrance. The length of the grotto is approximately 4 km but only few hundred metres are accessible to visitors yet this is ample distance to marvel at the spectacular caves, caverns, tunnels and underground lakes, all surrounded by some of the most amazing stalactites and stalagmites. It is a must see.
