We have been to Lido di Ostia and Pontile di Ostia during our trip to Rome. We wanted to see how the seaside outside the town is and since the place was the closest (easy accessible my train with a 1,5 euro ticket) we decided to give it a try. Pontile di Ostia is a very nice bridge, full of teenagers and couples, situated in the middle of the beach.
We spent there a great relaxing afternoon after the car horns and loud voices of Rome.
The only issue is the cleanliness of the place: at every 3 metres you can see bags from McDonald's or Hamburger boxes, beer cans and so on.
It is quite small, but cozy and if you catch one of the many days with sun - your batteries will be instantly recharged.
