"Hm…let's circle back, take a deep breath and start all over from the beginning. I know exactly what Civita is and is not."
Good advice. It's amazing how quickly misinformation and false assumptions can appear in just one seven-post thread.
Even though you're not staying in Civita di Bagnoregio, I can highly recommend the experience to readers who stand among the true adventurers. My favorite place to stay is Corte della Maestà. During certain hours, they will provide an electric vehicle for your luggage. The cart is it not permitted to take passengers. The Corte della Maestà serves one of the most glamorous breakfasts I have ever had in Italy.
If you stay overnight in Civita di Bagnoregio, you do not have to pay the €1.50 to cross the bridge. Even if you did, the cost is only €1.50. If you stay overnight in Civita di Bagnoregio and you have a car, you are permitted to park in the convenient parking lot beneath the pedestrian bridge. This is the closest parking lot to the bridge.
While it's true that many tourists simply drop in for five minutes to say they've seen it, staying overnight is an experience unlike any other. One night would never be enough for me. I love the precious solitude of Civita di Bagnoregio during late night and early morning.
The pedestrian bridge is not for all visitors. The climb will demand a cardio workout from everyone who dares to ascend. If you have a mild heart condition (and your doctor agrees), you can accomplish the climb, but you'll need to do it more slowly. No one will rush you or care how long you take. If you are disabled, seriously overweight, deal with bad knees or aching hips, or heart/cardio compromised, the challenging climb may not be good for you. If an accident occurred, I would not want to be on the pedestrian bridge or in Civita di Bagnoregio.
Civita di Bagnoregio can be a fascinating base for exploration, but getting to-and-from the car lot beneath the pedestrian walkway will require a serious amount of fitness capability.
My two favorite places to eat in Civita di Bagnoregio are Alma Civita and L'Arco del Gusto. L'Arco del Gusto sells local food items that no other store seems to carry. I go there simply to purchase some of my one-of-a-kind favorites. They make the best gifts for some of my food snob friends.
With a car, there are other spectacular places to stay in the area, but if you plan to visit Civita di Bagnoregio, then you need to prepare yourself for the lengthy walk or the amount of stairs necessary to get from your car to the pedestrian walkway.
I'll add more when I have time.
