The access tunnel was originally constructed to facilitate the transport of minerals from the nearby mines to the coast.
The beach is located within the Parco Geominerario Storico e Ambientale della Sardegna, a UNESCO-recognized site.
The cliffs surrounding the beach are composed of Cambrian limestone, some of the oldest rocks in Italy.
Due to the steep seabed, the water depth increases rapidly a few meters from the shore.
Spiaggia di San Nicolò is a scenic coastal stretch located in the municipality of Buggerru on the southwestern coast of Sardinia. The beach is characterized by a mix of golden sand and pebbles, flanked by high, rugged cliffs that define the Iglesiente coastline. It is primarily accessed via a tunnel carved through the rock, which historically served the nearby mining industry. The beach is notable for its deep blue, clear waters and is a popular spot for surfing and windsurfing due to the prevailing winds. The surrounding area features abandoned mining ruins reflecting the region's industrial heritage. The beach is exposed to the open sea, resulting in significant wave action during windy conditions.

Bring sturdy footwear, as the beach transition from sand to pebbles and rocks can be uneven.
Check local wind forecasts before arrival, as the beach can become very choppy for swimming when the Mistral wind blows.
Bring your own shade equipment, as there is very little natural canopy on the beach itself.
Attempting to swim during days with strong offshore winds, as the currents can become dangerous for inexperienced swimmers.
Respect the protected status of the geological site and do not remove rocks or mining artifacts.
