Sardinian nightlife is almost entirely a July and August affair, split between the expensive Costa Smeralda clubs in the north-east and the ordinary year-round bar life of Cagliari in the south.
Phi Beach, Baja Sardinia
An open-air club on the rocks at Localita Forte Cappellini in Arzachena, on the Costa Smeralda, where sunset DJ sets run into a full club night and there are restaurants on site. Summer season only, and it works on tables and bookings rather than a queue at the door.
Ambra Night, San Teodoro
The big summer club on the north-east coast, running roughly midnight to 6am with international DJ bookings through the season. San Teodoro itself is a low-key resort town, so the club is the reason people drive over.
Porto Cervo
The Costa Smeralda marina, and the most expensive night on the island: dress codes, table minimums and bottle prices to match. It is effectively a two-month town, busy in late July and August and largely shuttered either side.
Marina quarter, Cagliari
The lanes behind Via Roma, between the port and the Castello walls, hold Cagliari's year-round wine bars and small places, with Via Sardegna as the spine. Prices are ordinary Italian city prices rather than Costa Smeralda ones, and it works on a Tuesday in February.
The off-season reality
Outside roughly mid-June to mid-September most of the coastal clubs, beach bars and resort towns are closed, and several are boarded up entirely. If you are here in spring or autumn, nightlife means Cagliari, Sassari or Olbia, not the coast.
