This small boat offers free cruises on the Rhone every 20 minutes, during the months from March to November. The Avignon cithy council makes this service available to citizens so they can visit the island to play sports or retrieve their cars, since most people don't park downtown due to lack of spaces. So, there's either a free bus or this nice boat. The boat seems so small on the river, and it's pretty impressive since the current is very strong and the poor boat is right there struggling along. You also get a very beautiful view on the bridge of Avignon. Since there aren't many tourists, the boat is not crowded and there is almost never a line. You also have a good view of the palace of the Popes, and you can return by the free bus which leaves from the parking lot.
