Should I add a stone to a cairn when I reach the summit?

No, the modern advice is to leave the rocks where they are. While adding stones was historically important, the sheer number of hikers today means removing stones causes serious erosion and destroys microhabitats for alpine insects and mosses.

Why do some hills have no cairn at the top?

It usually means either the hill is so rarely walked that no one has bothered building one, or the summit is so vaguely defined that even locals couldn't agree where to place it. These "honest" hills can be disorienting because you're left pacing around trying to figure out if you've actually reached the highest point.

What does the word cairn actually mean?

It comes from the Scottish Gaelic "càrn," meaning a heap of stones. The word has survived almost unchanged for millennia across Celtic languages because the thing it describes—a deliberate pile of stones marking human presence—is just as permanent.
