Alternative Rome- What to do when you've done the "big things?"

I posted these for someone else:

Look into bike or segway tours. There is Gladiator training.
Head out late at night in Rome – when all the tourists have gone home safely tucked away in their hotel room beds and see the sites. Visiting the Trevi Fountain at midnight is magical – and probably the only time that you can get an unobstructed photo of the iconic fountain!
take a Vespa Tour by night
read these and ideas here
Here are a few more tidbits I found:
Trastevere – Viccolo de Cinque street between the Ponte Sisto and Ponte Garibaldi bridges is crowded and lively on the weekends. Cheap food, people drinking on the bridges, on the church steps — you’re sure to have some fun if you hang out in Trastevere. Try the Akab Club for electronic and occasional indie rock nights.
San Lorenzo – Just a ten minute walk down via Marsala. It’s near the University so lots of young trendy folks around. There is a club or two and plenty cheap foods. Try the pizza at Formula One!
Pigneto – This neighborhood (just further south from San Lorenzo) is one of thew newest hotspots for Rome locals. Wine bars and restaurants are the main fare here.
Madonna dei Monti – The Monti neighborhood is probably THE hipster area of Rome. There are some great mens fashion shops and cafes worth visiting during daytime, but visit the plaza at night to see the real fun. There’s a local drink shop where most people just buy a cheap beer to enjoy while sitting at the fountain.
Campo de Fiori - Lonely Planet describes this plaza as the place where you’re most likely to find drunk Romans. With street buskers and heaps of restaurants, it was a cool area to hang out in the evening but it still felt a bit too touristic. Better to visit this square to mark it off your “been there, done that” list, and then head over to Trastevere where all the real locals are.
Perhaps others can chime in on these.

Rome is so much more than the big sites. It has hundreds of sites worth seeing. You should probably grab a guide book and start reading up on what else the city has to offer. Between all the great museums, churches, piazzas and lesser visited sites you should easily be able to fill your week. I would suggest checking out the Baths of Caracalla, the Ara Pacis and the Cinecitta Studios.

Think about a walk through the Trastevere neighborhood with either lunch or dinner. We stayed there with the RS South Italy tour last fall and really enjoyed the vibe of the neighborhood. Also, be sure to walk through the Jewish Quarter. RS guidebook has info to guide you through. Neighborhoods in any large city offer great insight into everyday life and the people's history.

Without a doubt, Palazzo Valentini and/or Case Romane. You might also like the book "Rome the Second Time." See their website at RST.

On my second trip to Rome I did some wonderful walking tours: http://www.eatingitalyfoodtours.com/ offered a great culinary crawl in Trastevere either day time or twilight - learned much about the community and tasted fabulous food and wine - small tour group of less than 10 was really nice. Plus, you can chat with all the culinary owners/staff in Italian! Also took underground tour with http://www.througheternity.com/cities/rome-group-tours-rome-private-tours-rome - great perspective of all the eras/layers Rome is built on - guide Mario was amazing and we were a very small group, which allowed us to keep moving and see so much! Departs from San Clemente church in Colosseum neighborhood. Both tour meeting and ending locations were easily adjacent to public transport or nearby taxi stands. Rick Steves offers readers of his Rome book discounts with both these tour operators and he recommends these tours. Both easy to reserve on-line; culinary tour popular - reserve early. Consider one of these walking tours while in Rome and see another side of the Eternal City! Ciao` Diane

Speaking of the San Clemente Church in the neighborhood of the coliseum___if you have not seen it I highly recommend it. If you have not been to Ostia Antica, like ruins and have the time for a short train ride still within Rome, very open, airy. You probably have visited these but just in case.

Good idea for a post. I'm sure many of us will enjoy reading all the responses.

As an addendum to Christie's post...if you don't already know, please note that the trevi fountain is undergoing restoration and as such Is pretty much under wraps. There is a walkway that you can walk on apparently and see, but you don't want to go at midnight only to find it less than magical.

Not sure if anyone mentioned via Appia Antica (NOT Ostia Antica) - we did it on our first trip to Rome in 08 and it was one of the highlights. Caught a bus from the Colosseum and got off and saw the catacombs at San Sebastiano and wandered up the road past ruins, there was a neat arch. site where I think they were uncovering the floor plan of a house (this was 6 yrs ago) and walked up the ancient Roman road. There are bike tours out to the aquaducts (didn't do). We are def returning when we go back next month.

Ostia Antica

Because you said you already know Trastevere, I'm not going to recommend Trastevere.

Consider staying in Testaccio. Outstanding restaurants, not many tourists, easy access by bus to lots of places, and you'll get lots of chances to practice your Italian.

Another option: check out Villa Torlonia and the surrounding grounds and buildings.

And have you done the Baths of Caracalla and/or the Appian Way yet?

I am loving these suggestions. We love Trastevere but are intrigued to find out more about Testaccio. Also, we've never considered the film studios. I agree that Ostia Antica is a great trip along with Tivoli and I realize, reading these, that I have never walked Appia Antica. Thank you everyone and please keep the ideas coming! They are wonderful.

If you have done the big sights. I would suggest any of the following....
St. Peter in Chains Church
Castel Sant Angelo
Capuchin Crypt
Appian Way by bike
Catacombs of SAn Sebastiano or San Callisto
attend a soccer/football game
Ostia Antica
Tivoli
Some are day trips but several of the above I haven't been to yet and I've been to Rome numerous times.

Before you do the Appian Way by bike, be sure to look at what that road looks like using Google Maps Streetview. Bumpy does not begin to express it.
