Sulcis cycling route among mines and lagoons

South-west Sardinia is one of the island's most fascinating and least talked-about areas. The Sulcis-Iglesiente is a hard land, marked by a mining past that shaped its landscapes and villages, and by coastal wetlands where nature has reclaimed the upper hand. This is not the glossy Sardinia of the covers: it is raw, authentic and little visited, perfect for anyone seeking slow cycling made of industrial history, flamingos and roads where almost no one passes.

The mines of the Iglesiente

The thread of the journey unites two souls of this territory. On one side, the mining heritage: for over a century the Iglesiente was one of Italy's most important mining districts, and today it remains an extraordinary landscape of shafts, ore-washing plants, workers' villages and abandoned installations, recognised as a geo-mining park. Symbolic stops are Iglesias, historic capital of the mines, and the sites along the coast such as Masua, with the famous Porto Flavia carved into the cliff, and the spectacular Galleria Henry near Buggerru. To cycle among these places is to travel through the memory of gruelling labour, still legible today in the rusting structures overlooking the sea.

The coastal lagoons

On the other side are the wetlands of the Sulcis, the coastal lagoons that host a wealth of wildlife. Towards Cagliari and the southern plain, but also along the lagoons of the lower Sulcis, you come across expanses of brackish water where pink flamingos rest and nest, alongside a great variety of waterbirds. These are delicate, silent environments, ideal to skirt by bike on flat roads, stopping to observe without disturbing. The contrast between the iron-tinged mines of the interior and the lightness of the coastal lagoons is what makes this itinerary unique.

Difficulty and terrain

Technically the effort varies. Along the lagoons and coastal plains you ride flat or nearly so, on quiet, low-traffic roads; as you approach the mining Iglesiente the terrain turns hilly and mountainous, with some steep climbs to reach the sites clinging to cliffs and slopes. The total elevation gain therefore depends on how far you venture inland: you can build a gentler route staying near the coast and the wetlands, or a tougher one seeking out the high mines. The roads are largely paved and lightly trafficked, with possible gravel connections towards the mining sites, so a gravel bike or a sturdy touring bike is the right choice.

To get there, the reference points are Cagliari to the east and Iglesias as the heart of the area; from there you reach the coast at Masua and Buggerru and the lagoons of the Sulcis. It is best to pick a base and move in loops, alternating days devoted to the mines with more relaxed days along the lagoons.

When to go

The best window is wide: from spring, from March, to late autumn, through November. These are the months when the climate is mild, the lagoons are full of birds and the light on the sea and the mining ruins is softer. Precisely because the Sulcis is not a mass beach destination, you can ride even in the shoulder months and in deep autumn, finding open roads and near-deserted sites, while the rest of the island is by then empty or still focused on the best-known beaches. High summer brings intense heat and should be tackled with care, making the most of the early hours of the day.

A practical tip: arrange in advance your visit to the most scenic mining sites like Porto Flavia and the Galleria Henry, which are visited on guided tours with times worth checking, and leave the bike to explore them on foot. Always carry enough water, because there is no shortage of isolated stretches between villages, and respect the wetland environments by keeping your distance from the flamingos: in a territory so fragile and so little travelled, the finest journey is the one that leaves everything as it was.
