First DON’T take anything that you don’t want stained, torn, or that you might not want to put back into your suit case. I have a lot of shoes that are left in the flats after the fiesta as people do not want there anywhere near their other clothes. WE often get a whole new wardrobe from clothes that are left as well.
Pamplona is dirty and smelling during san fermin. The streets are washed everyday and that water from the streets always ends up on your pants and never comes out.(not to mention the red wine)
Buy inexpensive clothes if you are bringing your own. They sell drawstring pants in the streets and most people wear white T-shirts you can also obtain these as well as the scarves and shahes. If you are a Large person Xtra tall or Extra around you may want to bring you own as the spanish are on the small side and finding sizes to fit may be a problem.
Traditional wear is white pants or pants/skirts for the ladies, white shirt red shash red scarf. As more and more people come to the fiesta, it seems the less people are willing to wear what is traditional. This does not please the people of pamplona. They are trying to hold on to the tradition of the fiesta, so as I tell people this is their city their fiesta and we are their guests, the least we can do is to try and honor their tradition.
I get a lot of men that say they wouldn’t be caught dead in white pants. Well it isn’t after labor day yet and everyone else is wearing them. Join the people of pamplona and share their joy.
Now I will get off my soap box!
The other thing that is a must is good sturdy shoes. NO sandals as there is broken glass everywhere. If you want to be an idiot and run the risk of slicing your foot open be my guest. White tennis shoes fit the bill, again don’t pay $200 for a pair of running shoes, if you run, you are only running about 10-30 seconds, and as I said a lot of people abandon their shoes as they are often very nasty.
A lite jacket or sweatshirt is a plus as it can often get pretty cool during the wee hours of the morning. A long shleve white shirt works well too it will shade you from the sun and keep you warmer at night.
It can rain during the fiesta and often does. The early morning can be pretty cool as one morning on my way to the run I could see my breath as it was so cold. The days can get rather hot but the nights usually cool down.
