Hi everyone, I apologize if this question sounds stupid. My parents and I want to go back to Italy next September of 2019 and want to see some hill towns. My mother got very ill back in 2015 and had to have her heart valve replaced and she also suffers from arthritis in her back. We went to Scandinavia last August and she was in a lot of pain walking all day. My question's are: Are many of the hill towns pretty walking accessible and also if we have a car does it take a lot of walking to get inside the towns? We read that the hill towns do not allow cars inside. I just want my mother to be comfortable walking and not too far distances and lots of hills inside the towns. Thanks!
