Pack for the same weather as here, although it may be a few degrees warmer if your home is in the North! Kent weather should be about right. Expect to speak French in this area of Belgium
If you are planning on visiting Battlefields, memorials and cemetaries you need to do your research before you go. There are areas where you can just happen upon sites but they aren't all very well marked or explained.
This appears to be quite a useful site
Presumably you're going with someone who has an interest? Make sure to check what they want to see and get maps, directions and guides in advance. It can be a bit frustrating to visit sites without really understanding what you are looking at. The battles of the
Western Front covered a huge area so prepare to cover the miles, there are multiple locations and thousands of gravestones and names listed on the memorials. If you are interested in architecture Thiepval Memorial is an astonishing piece of design and a truly humbling experience, it
"contains the names of 73,357 British and South African men who have no known grave and who fell on the Somme between July 1916 and 20 March 1918"I have little or no known connection with the fallen but I found my trip a very emotional one. The bright well kept cemetaries are frightening in their sheer numbers and it's hard to grasp that these young men were killed in such a short space of time. If you do your research you'll find it a memorable experience and one that will affect you for years to come.
