The last time I encountered a herd of Highland cattle was when we were sea kayaking in the Outer Hebrides a few years ago. We had paddled to the island of Great Bernera and stopped for lunch. I went off to explore the island's ruined chapel and found myself surrounded by about a dozen over-curious bovines. They were quite agressive and determined to see us off their turf, which they did. We weren't going to argue! These Peak District cattle were rather more friendly, but it seems to be a characteristic of Highland cattle that they are naturally inquisitive.
I came across this herd near the Eagle Stone which can be seen on the distant left of the middle image.
