Best way to get from St. Peter's Basilica to Campo de Fiori?
 

We prefer to walk, but what route do you recommend and how many minutes will it take?

Hi K,

Enter your addresses at www.mappy.com and change "express" to "pedestrian".

I don't have strong opinions on the stretch from St Peter's to the Tiber but my trusty DK Eyewitness guide says "it is enjoyable to stroll the old narrow streets on either side of Via della Conziliazone"
What I can recommend from personal experience is a walk along the Via Giulia once you have crossed the river. This route was laid out by Bramante in the early 1500's and was one of the first straight streets in Rome. The Eyewitness guide has a walking tour that takes an estimated 1 hour if you go from the end by the Tiber to Ponte Sisto--but that would include stopping to look at the 20 points of interest marked in the guide.
You could cut off from the Via Giulia toward the Campo on the Via del Pellegrino or go farther to via dei Farnesi up to the Piazza Farnese then to Campo de Fiori.

Mappy is a good choice for walking route. If you're going in the summer and you're tired after a day of touring we found cabs to be inexpensive and convenient. We walked alot, used the metro where we could, took buses, however, after a day of touring we decided to cab around to sites. Fast, convenient, easy.

I second the via Giulia.

(Avoid the cors Vittorio Emmanuele -- much too busy to be pleasurable.)

Alternatively, once you cross the Tiber, take the via dei Coronari to reach Piazza Navona, then head south, crossing the corso VE, to get to the campo de' Fiori.
