It was even better than I thought it would be. Listening to Rick Steves' audio guide ahead of time totally helped with navigating around the site. I also purchased a very thorough map (Ostia Antica Modern Passion) for a few euros that was recommended at the ticket office. It came in very handy because it's actually quite a long walk, and almost impossible to see everything in 3 hours. This map actually helped in prioritizing the must see sights. Our online ticket timed entry was 9:30am, but you can just purchase it there. There really wasn't a whole lot of people around on a weekday. There's a free public restroom and vending machines with water next to the ticket office. The only other restroom is near the café.
Just start on the main road and work your way up. Everything is well marked with interesting facts and descriptions. It was amazing to see the well-preserved buildings and mosaics intact. It didn't seem like that in Pompeii. Then again, this ancient port city had been covered by sand dunes for centuries compared to a pyroclastic flow & ash. It's great that some of the dedication plaques and mosaics have not been unearthed and placed in a museum. Most of them are the originals. The statues and other artifacts are in the museum on site. Do not leave without visiting that museum. It's next door to the café.
What I love is that they have steps leading up to viewing points. There was one at the Baths of Neptune and another near the Thermopolium of Via di Diana. Take advantage of these viewing areas. You'll be amazed at what you can see up there. There is one at the Theater overlooking the Plaza of the Guilds, but the theater is currently under renovation or construction. I didn't get that chance, but there is a lovely view of it from the corporate guild as you're walking around that square. It was interesting to look at all the mosaic merchant signs. You can get an idea of what they were selling by the picture & design.
I'm not going to ruin it for you. There is so much more to see and write about. It's a must visit in my opinion. Especially if you're into seeing what Roman city life was like back in that time period. There are birds and flowers all over. Mainly just poppies that randomly pop up here and there. It's peaceful & quiet compared to Ancient Rome. I don't think many people know about it. There is a cute café, bookstore, and museum past the warehouses (Horrea) to the right towards the Tiber River. It was a very relaxing time. Check it out if you're staying anywhere near the airport.
