If you don't have a lot of time to spare when visiting Avignon, The Petit Train Avignon is one of the best ways to see what this charming city has to offer.
It might be difficult to cover all the attractions on foot when you are pressed for time, so this is a great way to have an overview of these attractions and the quaint, cobbled streets.
For us, this 45-min ride was worth it. It was enjoyable and relaxing. It could get bumpy though on some areas because of the cobbled streets along the route. It might trigger a little motion sickness. (My apology for the shaky videos - some parts.)
You can find the main station at Place du Palais. The rates and schedules are displayed there. I have also tried to show it on this video. Plus the list of sights to see along the way. They actually give you a little map for this.
