The name is Catalan and it means seagull. The beach of Porto Alabe is a wide expanse of compact medium-large grain sand, of various colours, from white to golden yellow and ochre, that looks out onto limpid waters that vary in colour from emerald green to blue and, behind it, there is a background of sand dunes covered in Mediterranean greenery: it is the gem of the Tresnuraghes seashore. Moving along the six kilometres of Provincial road 83 that separates the village of Planargia from its marine district of Porto Alabe, you will have the impression that you are quickly passing from evocative hilly, agricultural and pastoral landscapes to the blue of the sea, which is decorated every year with the five sails of the Legambiente Blue Guide. Cliffs surround the edges of the beach, the final part of the rias, or volcanic hills with terraces gently descending to the coast. The waters are shallow and the seabed slopes gently, making bathing easier and is ideal for families with children. There is parking and there are refreshments points close to the beach.

Going beyond the promontories that delimit it, you will find numerous and isolated little beaches of fine pink sand. In order to catch get to them, from the car park, you can follow convenient trails along the rocky crags. As well as the smaller coves, Porto Alabe stretches for several kilometres: it is one of the longest sandy stretches in the Planargia and Montiferru regions, after Bosa Marina (ten kilometres away). The coast of Tresnuraghes takes up a total of seven kilometres. Along with the sand, there are tall sea stacks, on top of which the Aragonese built a coastal defence system consisting of the Foghe tower, near the mouth of the riu Mannu, and those of Ischia Ruja and Columbargia. The natural harbour of Foghe was always a landing place for invading Moors and pirates. In Antiquity it had already been a landing place for the Ciddilitani of Roman origin and the Euticiani from the Greek island of Euboea. Here, the ancient town of Ciddilis may have appeared.

Tresnuraghes owes its name to three nuraghi that were once near the village: only traces of one of them still remain. However, there is abundant evidence of the Bronze Age in the territory: the nuraghi of Martine, Nani and Tepporo and a Tomb of Giants along the road leading to the church of san Marco. Near the rural sanctuary, you will also see proof of the Neolithic period: domus de Janas and the dolmen su Ju Malmuradu (meaning petrified saddle). In the centre, the houses are mostly low and they were built around the parish church of San Giorgio Martire, one of the numerous churches in the village. Both in religious and nonreligious contexts, you can taste Malvasia, the well-known DOC wine. The Casa Deriu museum is a must. Here, you can go on a journey back in time through the history of journalism, the Sardinian press, fashion, travel and bourgeois life in the 18th-18th centuries.
