It might be a goog idea to bring hiking boots, for you may decide to walk about the St.Victoire region, even if you don't go to the peak. What's more, Aix itself is cobbled mostly, and you may find them more comfortable on the cobblestones. Always bring spare shoes anyway, in case you tread in the dogpoo.
Toiletries and Medical Supplies: Bring medical supplies from home. My friend Ben came here with a cough, and the pharmacist gave him a missile shaped suppository (the pills that you put up your bum). When he took it back and explained that he would prefer cough medecine to not being able to sit down for a few hours, she became all defensive, saying "but it's really good, I use it, what's wrong with it?" The suppository, it must be said, is a lot more popular in France than in other countries...
Clothing/Shoes/Weather Gear: It's a good idea to have a scarf in Aix, especially from November to about April, because it can sometimes be chilly, especially when the Mistral comes to town. Here I am, with my beloved scarf from Monoprix, when it snowed in December 2002. I should add, you may not need to bring a scarf really, I bought mine in Aix. They have lots of nice scarves here, such as mine, or my other one, from Celio. But Eurodif, near the Rotonde on Ave des Belges, does lots of very nice inexpensive scarves; mainly for women though.
Clothing/Shoes/Weather Gear: The climate has made the reputation of this region. The winters are mild (an average temperature of 8°C) and its summers are hot and dry with temperatures varying between 22°C and 30°C. The rainfall is low, (less than 50 days of rain per year).
Miscellaneous: The fruit and vegetable market in Aix is a daily market held in the Place Richelme, between the post office and the old grain market.
