The Canal Grande of Nebida, halfway between Masua, a district of Iglesias, and Buggerru, is a long, narrow valley, along which the rivulet of the same name, meandering into the sea. The inlet is characterized by a little, secluded beach with pebbles, rocks and sand. It is almost never crowded and its seclusion and colours will make you feel like you are in a relaxing haven.

At the foot of the cliff, ravines and cavities open up. On the western side you will find the cave of Canal Grande, carved out by the sea, partially submerged and approximately 150 metres long. The tunnel crosses the promontory from one side to the other, just above the water.
