Conca Verde is an excellent location for your stay as all major locations of interest can be easily reached from here. Will you be heading north to Santa Teresa and the west coast, or south towards Porto Cervo and the east coast.
You must take a day to visit the inland towns like Tempio Pausania with its natural wells or simply go for a day trip at the Archipleago of la Maddalena.
In a really short distance there is such a concentration of activities like rural restaurants (agriturismo), fishing harbors, boat tours, shopping, bars, nightlife …or just a delicious fresh ice cream from the local gelateria.
