Get to the collesium early

Impressive architecture. Keep in mind that the ticket also gives you access to the Forum & the Palatine Hill & that all these sites close at 4:30pm, but the last entrance is at 3:30pm so you need to plan your visit carefully if you're going in the afternoon & you want to see all 3 places.

Pay in advance. The cue is 1hr+ wait. And there is a lot of “tour guides and staff” who try to sell you tickets outside the the ticket cue but of course for a crazy price. If you’re willing to spend more I was told you’d pass through with no cue and have ear pieces for translation. You can see most of the outside of the colosseum but not inside without paying.

Definitely worth buying a skip the line ticket in advance from the official website. We went in January and it took us 5 minutes to get in, with our advance ticket. Other people were queuing for over three hours.

If getting here via tram get yourself masses of time to walk to site,locals just seemed to send us everywhere rather than direct walk It’s a long walk.If prebooking tour get a midday one in order to get there on time if you arrive late they will not let you in.An afterthought would be get off tram and grab a taxi for last leg.
