Buggerru

Highlight • Settlement

Buggerru is a charming tourist village built on an ancient mining community founded in 1864. Today hosting around a thousand inhabitants, the town preserves the memory of its intense mining activity until 1979.

It develops in a radiant manner along the suggestive mouth of the valley of Mount Caitas, baptized with the name of the famous Malfidano mine, the flagship of the mining industry between the late nineteenth and early twentieth centuries. This location was already known by the Romans for the presence of silver. The modern port is dominated by the entrance to the Henry tunnel, today an open-air museum, once crossed by a train used to transport the extracted mineral. It was nicknamed "petite Paris" for the environment recreated by the managers and their families, belonging to the French company that managed the mining activity. Its history is complex, marked by strikes and social tensions in the context of the mining industry.

Its enchanting coastline, with Buggerru beach on the right of the port, offers breathtaking scenery over the blue sea.

Planu Sartu Mine

Highlight • Historical Site

The Planu Sartu mine is located on the limestone plateau west of Buggerru. Discovered in 1869, it reached its peak in the early 20th century, employing over 2,700 workers. Calamine, a zinc ore, was mined here, processed both open-pit and underground. The Henry Tunnel, still visible, connected the underground worksites to the Buggerru washery. Operation continued until the 1950s, when the deposits were exhausted and the mine closed permanently.

Euphorbia Characias in Sardinia

Highlight • Natural

The densely growing Euphorbia characias, with its bright yellow inflorescences and gray-green leaves, dominates the Mediterranean maquis of Sardinia. As an adaptation to summer drought, this spurge species has developed a white milky sap that, when damaged, oozes and contains toxic diterpenes. The complex inflorescences consist of seemingly simple flowers that are in fact specialized inflorescences (cyathia) with individual male and female flowers, surrounded by striking bracts. As an important component of Mediterranean sclerophyll vegetation, it contributes to biodiversity and provides food for specialized pollinators early in the year.

Tunnel to Cala Lunga

Highlight • Structure

The tunnel for Cala Lunga is a short excavated tunnel that was originally built to facilitate the transport of minerals to the more sheltered Cala Lunga, allowing boarding when the sea conditions at Cala Domestica were unfavorable.

It has now become an evocative tourist attraction that allows you to quickly move from one beach to another. However, you need to be careful of the uneven and slippery terrain, both inside the tunnel and along the cliff path to reach it.

Cala Lunga (Cala Grande)

Highlight • Beach

A small rock tunnel leads to Cala Lunga (Cala Grande) to the right of Cala Domestica. Cala Grande seems a bit exaggerated, as it is a small, enchanting bay. It used to be used as a hideout from pirates, because it cannot be seen from the sea. The beach is beautiful, natural and relatively lonely.
