Growing opposition to mass tourism has prompted fresh protests on the Spanish island of Mallorca, where campaigners fear new planning rules could lead to increased development along protected coastal areas. Thousands of demonstrators formed a human chain at the unspoilt beach of Es Trenc, arguing that relaxed regulations could allow more hotels, tourist facilities and infrastructure, threatening one of the island’s most valued natural sites. Regional authorities reject these claims, insisting protected areas remain safe. The protest comes ahead of wider demonstrations against overtourism, as many residents say rising visitor numbers are driving up housing costs, overloading transport and public services, and making everyday life increasingly difficult. Mallorca welcomed more than 13 million visitors last year, far exceeding its resident population. While tourism remains vital to the island’s economy, campaigners are calling for measures to reduce visitor numbers, regulate holiday rentals, and preserve both local communities and the natural environment.
