We arrived in the mid afternoon and we managed to visit several sites in the early evening. It helps out quite a bit when the sun sets around 8:30pm and without kids. On family trips with the kids, I only manage to get 1/3 of the things I want to photograph or do, but on this trip it seemed like we managed to get almost all of it done in one afternoon! I remember thinking to myself that I may have booked too many days for this trip! Or another thought is I am more efficient than before.
One of the sites that you think of in Roma is the Colosseum. Gladiator the movie also comes to mine. We hit that iconic location first after dinner.
Next on the list nearby the Colosseum was the Roman Forum. This area contained a lot of the remaining old columns and ruins. Way in the back of the images, the Colosseum was poking through.
