The Balearic Islands are known for their beautiful beaches, natural landscapes and cultural heritage. However, one practice that has become popular among tourists is building stone piles, also known as “stone stacking”. Although it may seem a harmless activity, this practice has several negative impacts on the islands' natural and cultural environment.
As if that were not enough, every year approximately one tonne of stones and sand is confiscated at the airports of the Balearic Islands. For example, at Menorca airport, 987.55 kg of geological material, including stones, sand and fossils, was confiscated in 2024. This practice of collecting stones and sand as souvenirs has a significant impact on the islands' natural environment.
Environmental impact of these actions:
Soil erosion: Stone piles can contribute to soil erosion. When stones are moved from their original position, the ground is destabilised, increasing the risk of erosion and soil degradation.
Habitat disruption: Stones are part of the natural habitat of many species. When they are moved, natural shelters for insects, reptiles and other small animals are destroyed, disrupting the local ecosystem.
Visual impact: Stone piles can alter the natural landscape, creating an artificial image that detracts from the natural beauty of the Balearic Islands. This can affect the experience of other visitors who want to enjoy an unspoilt, natural setting.
Plundering of stones and sand: As well as building stone piles, many tourists collect stones and sand as souvenirs. This practice contributes to the loss of natural resources and can have a significant impact on the morphology of beaches and other natural environments. Removing stones and sand upsets the natural balance and can speed up erosion processes.
Cultural impact
Destruction of heritage: In some areas, stones may be part of historic buildings or important cultural features. Handling them can damage these features, contributing to the loss of cultural heritage.
Respect for local traditions: Building stone piles is not part of the local traditions of the Balearic Islands. This practice, introduced by tourists, can be seen as a lack of respect for local culture and traditions.
Sustainable alternatives
To protect the natural and cultural environment of the Balearic Islands, it is important to promote sustainable alternatives. Tourists can enjoy nature without leaving a trace, following the “Leave No Trace” principles. This includes not moving stones or altering the natural environment, thus respecting the islands' flora, fauna and cultural heritage.
