Corso Nazionale is Termoli's main pedestrian street, a useful place to feel the town shift from beach resort to everyday social centre. Shops, cafes, restaurants, and small side streets run off the corso, and weekend evenings bring the local passeggiata.
It is best combined with the old town, cathedral, and waterfront rather than treated as a sight on its own. Come in the early evening, when the street is busy and the town feels most awake.
