Miscellaneous: Rain is an important word in Nantes.
Nantes could definitely contests as one of France's rainiest place.
I remember the long long autumn and winter months when rain was falling on a pretty daily basis. If it does not rain in Nantes every day, it is a good thing. Otherwise, it is natural.
So, be aware that when you travel to Nantes between from October to March-April, you may have rainy days.
Good point is that it is never really cold there. Rare when days are under 5 degrees.
Clothing/Shoes/Weather Gear: I don't know if it is typical of Nantes, but I studied abroad there in the spring of 2001 & it rained a lot. We often times compared the weather to Seattle. Definitely don't go there without an umbrella. It may not be quite as bad during other times of the year, but I wouldn't consider going to Nantes without an umbrella.
Luggage and bags: Bring along a backpack or sportsbag. It's more handy on a campground then a suitcase.
Clothing/Shoes/Weather Gear: Dress lightly in summer, but always bring along a pair of long trousers, a sweater, some good walking shoes and a light coat. Because in the evening the temperature might be a little lower then at brought daylight.
Toiletries and Medical Supplies: Bring suncream and anti mosquito cream.
Photo Equipment: Film is available here.
Camping/Beach/Outdoor Gear: Campgrounds are nearby Nantes. For more information see my accomodation tips and TRAVELLOGUE!
You might want to bring along a sleepingbag...
