European tourist hotspots, including Barcelona, Rome, and the Canary Islands, are experiencing heightened tensions due to the negative impacts of over-tourism. Residents in these cities have staged protests, with actions ranging from anti-tourist graffiti and water gun attacks on diners to large-scale demonstrations against mass tourism. The situation in Rome is particularly dire, with locals like filmmaker Carlo Verddone contemplating leaving the city due to public urination, traffic, and garbage issues. Mallorca has seen cancellations from UK tourists fearing anti-tourism protests. Despite these tensions, Spain's tourism numbers are up this year, particularly in short-term rentals, exacerbating housing costs and gentrification. Authorities are considering tighter regulations on tourism to address these issues.
