- If you want to explore then I would say you would need a car. We went to Bergen Belsen which was a POW camp and then a concentration camp during WW2. Some of the photos were horrific so I had to steer my 9 year old away from them. The town of Celle is lovely as is Bremen. My daughter got quite a few bites I think from playing in the sand at the park so remember good insect repellent!
