Neptune's Grotto (Grotta di Nettuno) Highly Recommended Highly Recommended Highly Recommended : Michelin's recommendations

Discovered in the 16C by fishermen, a 600m circuit of the cave has been open to visitors since 1954. Whatever the season, the temperature remains between 18 and 20°C. The water that penetrates the cavity forms the Lago Lamarmora, which at 100m long is one of the largest saltwater lakes in Europe. Light infiltrates at a single point in the cave; and there cave flora turn the walls green. After 153 steps, you reach the different chambers of the cave, named after the weird and wonderful shapes of their concretions (Christmas tree, basilica dome, organ).

    Review information

    • Language: fra
    • Position : As a couple


    L'entrée de la grotte est magnifique, nous avons pris les marches pour y aller, le panorama est splendide.


    Le bémol on peut accéder à l'entrée de la grotte mais pour aller plus loin il faut payer 12 euros par personnes! Eviter de prendre le bateaux pour y aller car celui-ci vous fait payer en général 15 euros, juste pour y aller et une fois là-bas vous payerez en plus 12 euros pour la visite.Et si vous décidez de prendre par les marches ce que nous avons fait, prévoir absolument une bouteille d'eau, les 656 marches sont impréssionantes et infinisable. Courbatures assurés le lendemain ;).
