This is the coolest thing we did in Rome.
The bike tour was a refreshing change of pace from the city, and allowed us to see many sights that are not easily accessible by foot. Dimitri was an A+ guide and an overall great guy. We learned a lot about the Romans and Roman life, in addition to getting fresh air, a nice workout and some great photos.
The Appian Way was a big highlight. All roads eventually led to Rome, but this road was the very first.
Via Appia Antica is not only historical but also exceedingly beautiful. We passed through several monumental Roman residences and catacombs, against the backdrop of open fields and rolling hills in the distance. It is no wonder many of the Roman elites chose to live outside the city. We even ran into a herd of goats!
We had such a great time we ended up spending longer at each stop than planned. Dimitri was super cool, and helped us take lots of pictures and videos.
The biking itself was not difficult, even with the occasional dirt path. You will not be tired, but will definitely cover enough distance to feel accomplished.
