joinable day trips to see tivoli and hadrians villa

Have googled and contacted a few tour operators in Rome but none have joinable tours that go outside of Rome. The only one I can find is Viator. Has anyone used a joinable tour service or know of one? We will be staying at a hotel in central Rome. The joinable tours from Romeinlimo are from cruise ports only. Thanks for your suggestions. :)

This is surprising to me. There are a ton of daytrips offered to Villa Adriana and Tivoli from Rome.

I just Googled "Hadrian's villa and Tivoli tour" and at least two agencies that have been recommended here in the past popped up. They are based in Rome so I assume that's where their tours would start.

I have not used either of them so I am not allowed to recommend them, but I suggest you do as I did and search for names on Google, then come back here or to tripadvisor to look for reviews of the companies.

I was googling "joinable day tours from rome" trying to get some ideas of where to go and not a specific title. That was my mistake. I did what u did and got several companies. Most were private tours but 2 turned out to be joinable. City Wonders and Enjoy Rome. Thanks. Have you ever taken the train to ostia antica? It looks like an easy one to do on your own. Always appreciate reading your suggestions :)

It's very easy to take the train to Ostia Antica. You can take the metro from Rome (Blue line) to the Piramide stop, where you transfer to the adjacent train station, which is called Ostiense. Look for the Roma-Lido train line, which runs at frequent intervals. Get on the next train headed in the direction of Lido and then get off at the station for Ostia Antica.

You can use the same metro ticket for the entire trip.

Once you get out of the train station, look for the pedestrian bridge over the busy road -- take it, then keep going straight and shortly you'll be at the entrance.

There's a very good tourist guide here: http://www.ostia-antica.org/touristguide.pdf
