There are a small number of sights that seem to make it on to every list of day trips from Paris. The two sights which seem to be on every list are Versailles and Monet's garden in Giverny.
Let's be honest: If you like Monet, or you have a real interest in flowers and horticulture, then you are going to love Monet's Garden. If you aren't interested in Money and don't really like flowers and horticulture, then this may not be the day trip for you
What to see
The park, officially called "Foundation Claude Monet" is made up of a number of elements.
The hightlights include the main chateau, which is now the Museum of Ile-de-France (the French administrative district which includes Sceaux and Paris). Hours and prices for the museum are here. They are in French, but it is easy to find the information you need.
Infront of the chateau is the Plane of Four Statues. It is a large open field which stretches out infront of the chateau to the far east side of the park.
To east of the chateau is The Cascades, a waterway that descends in steps with fountains dropping down from the main chateau to the grand canal.
The grand canal is approximately 1.1km/0.68mi around and is in the form of a long canal with a smaller pool called "l'Octogone" joined to the canal on the west side.
The park that surrounds the canal is full of trees and walk ways.
There are a number of cafes around the park, which have great vistas over the park and provide a nice place to stop and pass the time.
There is a plan of the park here, although the park is not difficult to navigate around.
