One of the great tomato fests or even pilgrimages is La Tomatina tomato fight, where people throw tomatoes at each other. I expect that wearing a white t-shirt makes it all the more fun!
La Tomatina (Bũnol, Valencia, Spain), held annually on the last Wednesday in August, attracts tens of thousands of visitors. The highlight is the tomato fight, in which 30,000+ participants throw an estimated 150,000 overripe tomatoes (100 metric tons) at each other.
