Stone stacking: the problem with stacking stones in nature
There is no denying the appeal of stacking stones in a beautiful natural setting. A perfectly balanced cairn beside a peaceful lake or with mountains in the background makes for a striking photograph. The process itself can also be relaxing, requiring concentration, patience and slow, deliberate movements often associated with Zen philosophy.
However, behind this seemingly harmless activity lies a lesser-known reality. Stone stacking is regarded by scientists and managers of natural areas as an unsustainable practice, especially when it becomes a widespread trend. Increasingly, local authorities and organisations responsible for protected landscapes are discouraging the practice because of its impact on the environment.
A striking example can be found near Playa de los Ingleses (Cementerio de los Ingleses), on the stage between Arou and Camariñas along the Camiño dos Faros. In recent years, the number of stone stacks has multiplied to such an extent that, in some places, they stretch as far as the eye can see. As the number of cairns continued to grow and alter the landscape, local authorities took action and even introduced fines in an attempt to curb the trend.
Moving stones disrupts small ecosystems. Many insects, spiders, reptiles, mosses and other plants depend on rocks for shelter, moisture and protection from the elements. By moving them, we disturb a natural balance that may have taken years, decades or even centuries to develop.
Stone stacking also goes against one of the key principles of responsible outdoor recreation: Leave No Trace. The best way to respect a landscape is to enjoy it exactly as it is, without altering it.
The next time you come across a stone on the trail, remember: don't move rocks, plants or any other natural elements. Enjoy nature as it is and help ensure that future visitors can do the same.
