From Amalfi, you can take a bus up to the exquisitely beautiful town of Ravello. It's not a short bus ride and the bus tends to be crowded since they don't run as often to Ravello. Also, there is one point along the way where the road is only wide enough for one vehicle (the other side is a sharp drop down the cliff.) Therefore, there's a long wait until the light changes in order to allow the other cars to go. So, if you get claustrophobic or aren't able to stand for a long period of time, I would recommend spending the extra money for a cab. However, once you get to Ravello, the views are simply captivating!
