I enjoy Agarcia's tip on petanque (boules), not to mention all of Agarcia's Arles pages in general
Click here and scroll down to 2nd tip "Petanque"
Equipment: Here is an introduction to the game:
Petanque for beginners
The amphitheatre holds bullfights. We lucked out and caught one such event the day we arrived. It wasn't the Spanish type, where the bull is killed...this type is called "course camarguaise", and is essentially a big game of "tag" between the bull and several "razeteurs", men wearing white who take turns tagging the bull on the head between the horns and running away. It all seems very well choreographed...the bull never quite catches the chaps. The men are not armed, and so rely on their wits to keep out of harm's way.
Equipment: Price was less than 10 Euros per person.
