The free Rome that costs nothing

Here's the budget traveller's secret: some of Rome's best moments are free. Toss a coin in the Trevi Fountain, climb the Spanish Steps, stand under the open oculus of the Pantheon (free to enter), wander the Forum's edges, and hike up the Gianicolo for the finest panorama in the city. String these together and you've got a full, glorious day that costs you nothing but shoe leather. We'll give you a walking route that links the best of them.
