In Pincio Gardens, there are places where you can rent bikes or a surrey- a four person bike, covered with an umbrella. Today we decided to give it a try. It was 5 Euros a person for an hour. We had so much fun riding around the Villa Borghese and Pincio Gardens. The bikes even had a small motor on them that made pedaling much easier, especially up hills. Unfortunately ours turned off periodically and at one point we had to get out and push ours up a hill. But either way, it was fun and it is definitely the best way to see the park.
