I wasn’t quite sure what to expect when I decided to go to Saint-Germain-en-Laye, except that there was a castle (and not a very pretty one). However, immediately after stepping off the escalator of the metro, I probably said WOW at least five times. We walked right into the Domaine National de Saint-Germain-en-Laye and there were beautiful views of La Défense and French style gardens. You can wander down quite paths in something between the woods and the forest, and we even found signs of fall. (Fall isn’t a flashy event here.)
If archeology interests you, the château is home to the National Archeology Museum (Musée archéologie nationale). For those who enjoy classical music, the home of Claude Debussy is located in the town center. Saint-Germain-en-Laye is quite pleasant, the views peaceful, and the walks enjoyable. I’d say it’s a good escape from the cramped Paris streets when you have a weekend to spare. Even the train ride over is relaxing, with views of the Marne river.
