You can of course use your National Trust (England/Wales) membership otherwise you may feel it a little more expensive that it need be for parking and entry.
However an excellent interpretation centre, well laid out and representing alternative viewpoints on the battle and the reasons for it happening, and taking place, at this location.
An audio guide is given to you to walk the battlefield, which covers a surprisingly small area. However the weather conditions at the time; very cold and with a biting wind, made us leave the scene very quickly. The audio guide was good but rather fussy, too many choices which you couldn’t always hear because of the biting wind. The guide seemed to have a mind of its own at times, and the `where am I now` gps button often had me located in the middle of the main road which ran alongside the battle site! Some marker posts on the field to match the ones permanently displayed on the guide would have helped.
Cafe has good range of reasonable priced food.
