In an effort to prevent congestion and encourage sustainable tourism, more and more regions throughout Spain are enacting limits on the number of visitors for some of its most well-known natural sites.
According to a survey by the Eco-union organisation, tourism in national parks has increased by 77 percent over the past 20 years, with around 16 million tourists per year.
During the Covid-19 epidemic, when both domestic and foreign tourists preferred to vacation to natural locations, away from people in the main cities, visitor numbers peaked.
Increased visitor traffic endangers natural environments by causing erosion, trampled plant species, and alarmed local fauna.

According to Pau Monasterio, a representative for Ecologists in Action, “Natural habitats need to be protected against enormous tourism that can destroy them, with legislation that allow their enjoyment but also guarantee conservation.”
There are restrictions on the number of visitors to places like As Catedrais Beach in Galicia, which is well-known for its spectacular rock formations, Mount Teide, Spain’s highest mountain, and Doana National Park, one of the most significant wetlands in Europe.
Which regions in Spain have imposed limits on the number of visitors?

The Ordesa y Monte Perdido National Park in Aragon has visitor limits in place for a long time and plans to keep them in place.

Limitations in the Balearic Islands have been extended to the Martimo-Terrestre de Cabrera National Park, which is home to 50% of Spain’s posidonia (seagrass) meadows. To enter the area by watercraft, special authorization is required.

The Balearic Islands’ government also employed environmental informants this summer to cruise the beaches and disseminate guidance and knowledge on the islands’ protected natural areas.
