Hello all. Looking to take another solo trip to Europe this May and I'm looking to focus a lot on WW2 battlegrounds, museums, and the like. France will be the main focus for the Normandy beaches and the associated museums, but of course I'll go to Paris. I'd guess there are some good war related sights in the city to see among all the other things but I'm not overly focused on the major tourist traps this time. I'd rather see tanks and fortifications than art. Wouldn't mind spending more time in out of the way places. My trips to the UK, Germany, and Italy were all pretty much standard tourist trap focused trips so getting off the beaten path a bit would not bother me. The UK is possible, I've been there but pretty much focused on the castles and big sites in London and up north. I know there are some some DDay related sites in southern England but not sure its worth diverting there. Any suggestions to major places I should go to focusing on the areas around France, Belgium, etc? Actual battlefields and the like are what I'm really interested in visiting.
Would this kind of trip necessitate renting a car or could I make due with trains and buses? I'm 44 and don't mind walking a fair bit.
Thanks for any tips!
