Perhaps not the best beach in Sardinia per se, but definitely one of the best urban beaches in the world, Poetto is the main beach in Cagliari. An incredibly long, sandy beach is surmounted by the scenic promontory of Sella del Diavolo (devil's saddle). Behind the beach, the beautiful natural oasis of Molentargius is a great park for a walk and a fantastic spot to observe the local fauna. In recent years Poetto has undergone lots of improvement works. A biking and running trail runs along the beach, which can be reached by public transport too.
