Okay, in the general theme of top threes:
Battlefield walks:
1) von Bredlow's Death Ride, Mars-La-Tours.
2) The Approach of the Prussian Guard, Saint Privat
3) The ridge and Lion Mound at Waterloo down to Le Belle Alliance


Others of note: Weddles Charge, Verdun, Passchendaele, The real Battle of Bosworth.

Not to be mentioned:
The British March from the town to canal at Mons (which is a dull, grey canal, the redoubtable Mrs Lemmey HATED that one).

The old walls at ypres are nice to have a walk on, right to the "menenpoort", where they play the last post daily!

Really nice to combine with flanders fields museum!!

1) The Swiepwald at Koniggratz;
2) von Bredow's Death Ride at Mars le Tour;
3) Wysokov at the Battle of Nachod.

mooched around the beaches in Normandy (did my dissisitation on the landings) but no specific walks to speak of

Pickett’s Charge, Gettysburg

Walking some of the siege lines at Vicksburg

-Bryan

battle of Berlin
Tumbledown
battle of the Somme (Thiepval memorial very thought provoking) 

would love to do Stalingrad!

1) Northern Sector of 1st Day of the Somme (WWI)
2) Towton (Wars of the Roses)
3) Dunkirk (WWII)

All of them have something different to offer and still give an impression of what happened there now. Wouldn't go so far as to say any of them are unspoilt but walking the ground of all three helped me appreciate what happen at these battles much more.
