I'm spending 5 days in Paris. I was thinking of doing a day trip to the vineyards but I'm not sure which vineyard is the nearest for a day trip. I have no preference regarding vineyards for champagne, red wine, white wine, etc. I've never been to a vineyard before and this is my first trip to Paris.
Besides vineyards, is there anything I should consider as a day trip? I've heard of Versailles, Chartres, Giverny and Fontainbleau. Which in your opinion is worth going to?
Is there any website I can look for a good Paris map?
