DH and I did an e-bike tour of the Appian Way, the Catacombs, and the Roman Aqueducts. Meet up around 9AM and back around 3PM. It was a fantastic way to see a different part of the city, as well as some other Roman historical sites more off the beaten path. We booked through the Red Bicycle tour company. We all stopped along the way for lunch. It was at an open-air market, with a family style picnic with pasta, salad, bread, wine, etc. There was even sparkling water on tap. It was a highlight of our recent trip to Rome!
