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

No. Building or enlarging cairns can worsen erosion, disturb habitats and damage archaeology. Leave stones where they are and report concerns about misleading or damaged cairns to the land manager.

Why do some hills have no cairn at the top?

There is no single reason. A summit may lack loose stone, a marker may have collapsed or been removed, land managers may discourage new piles, or nobody may ever have built one. Use your map and navigation tools to confirm the summit.

What does the word cairn actually mean?

English cairn comes through Scots from Scottish Gaelic càrn, meaning a heap or mound of stones. Related Celtic words include Welsh carn and Cornish karn, but the word alone does not tell you a feature’s age or purpose.

Why is it called that?
