My wife and I will be visiting some friends in Paris next summer and are thinking of taking one day to visit Normandy. Now we will be leaving from Paris that morning and coming back that night, so we are aware it's going to be ALOT of travel in one day, but we are on a very tight schedule. Our plan would be to take an early train from Paris (about a 2.5 hour ride?? correct me if I'm wrong). Then explore the beaches and any major sites for the afternoon and then head back later that night. My question is, does anyone have any recommendations on how we should go about exploring without using a tour guide? Such as: how do we get from the train station to the actual sites we visit? Any tips on the best sites we can use our time the best? Any other advice you would give on if exploring the sites by ourselves is do-able. I just would rather be on our own schedule than being with a tour. Thanks for the help!
