You are on the eastern coast and Isuledda beach is the gem of this strip of Gallura.  Its fine sand, transparent waters and scented vegetation make it definitely beyond comparison.  Only a few km. from Costa Smeralda, it's a land of unique and natural wonders.
Travelling along the main road from Posada to San Teodoro, it's possible to enjoy direct contact with the Mediterranean's clearest waters.
The climate is typical of Gallura: gentle breezes, tropical temperatures and very warm sunshine reflecting off the transparent sea.
The Sardinian north-eastern coast from Posada to Olbia is a continuous sequence of delightful inlets, the beaches are all easily reached, mixed in with granite rocks of extraordinary shape.  This coast is no less charming than that of the Costa Smeralda, it's just less advertised and promoted, less trendy and therefore less crowded.
Initially, it contained small cottages; today the actual villages are well-equipped tourist resorts, developed throughout the whole area.  Some good examples are Brunella, San Lorenzo, Solità, San Pietro, all small suburbs transformed into sought-after destinations for summer holidays.
Agrustos is another example.  During the Roman period, it was called Augustus Populus.  Today, it's a scenic village on the sea, characterised by its sandy dunes.  In the past, this coast used to be a shelter along the granite trade routes.  It's one beach after another, from Punta d'Ottiolu to Cala d'Ambra and the Tamerici village.  Going north, you'll come across La Cinta beach; three kilometres of sand separating the sea from the amazing San Teodoro pool, one of the most important on the Sardinian island.  There are surroundings villages, residences, camps and small holiday houses.  Opposite is the wonderful view of the Tavolara and Molara islands and the Capo Coda Cavallo promontory.  Here, the coast is a sequence of short, green hills, rich with pine woods and thick Mediterranean underbrush.
The scenery from Coda Cavallo village, hidden beyond the hill top, is one of the most beautiful in all of Gallura.  Cala Brandinchi, for example, is a not very famous beach but it offers a unique view, making the effort of getting there worthwhile.
The San Teodoro coast, bordering the Nuoro area, reserves other unforgettable emotions with Cala Girgolu, in front of Tavolara island.  On this island, the granite rocks have very peculiar shapes, reminding us of original, human works of art.  Unfortunately, one of the most famous of these rocks, the so-called Tartaruga (the tortoise), was decapitated by a vile tourist looking for souvenirs.
