South of Oplontis, Stabiae stood on the slopes of the Varano hill overlooking what was then the sea and is now modern Castellammare di Stabia. Here at Stabiae you can visit two villas: the 1st-century-BC Villa Arianna and the larger Villa San Marco, said to measure more than 11,000 sq metres. Neither is in mint condition, but the frescoes in Villa Arianna suggest that it must once have been quite something. Stabiae is a 1.1km walk south of Via Nocera Circumvesuviana station.
