Cala Luna is an enchanting bay and an estuary very frequented by summer maritime traffic. It is absolutely worth a visit, as it represents a true pearl of the Mediterranean with its light sand, turquoise water, numerous small caves and almost white rocks. It can be reached either on foot or by boat. The beauty of this bay is beyond compare. Here you can find shelter in the shade of one of the numerous caves or immerse yourself in the crystal clear waters, a true treasure of Sardinia. At the end of the bay, an oasis invites you to stop for a snack in the kiosk or for a picnic. Also watch out for bold goats grazing on the steep slopes! If the walk back seems too challenging, you can always take a boat back to Cala Gonone or Cala Fuili.

On the path between Cala Gonone and Cala Luna there are many caves that can only be reached on foot. The Oddoana cave is one of these. The atmosphere with the Mediterranean scrub and the cave is very suggestive. The cave is not very large and the path to reach its entrance is a bit steep. Alternatively, you can take a small detour that goes around the cave.
