I was there 30 years ago and walked up the field where Pickett’s Charge happened. There weren’t any signs saying it was off limits. I don’t know about now. I felt shaken just being there and trying to imagine the horrific slaughter. Those guys were literal cannon fodder.
you can still walk it there are paths
Pickett’s Charge Field is private property which is actively farmed, thus it is “off limits” for tourists. However, several years ago, there was a trail that was created so one could “walk the Charge” along an existing fence line that ran from the Confederate where the charge began to the High Watermark, or near it.
