Oops… Their website doesn’t directly answer this, but we have asked them and are waiting for their answer!
However, here’s what their website says:
“As part of the ongoing reorganization of the PArCo’s paths to make them accessible for all, an alternative to the Via Sacra is now available, permitting visitors to reach the main monuments in the Roman Forum (House of the Vestals, Temple of Romulus, Lacus Iuturnae, Temple of Antoninus and Faustina, Piazza del Foro, Curia). Reaching the summit of the Palatine Hill, although not particularly difficult, is still contingent upon several brief stretches of relatively steep paths and generally irregular paving throughout. Plans are underway to increase the overall length of the paths accessible to all from 1.5 to 2.0 kilometers.”
Baby changing facilities can be found in the Roman Forum.
The closest private nursing facility can be found at the Colosseum.
