In Lanzarote, a series of protests against mass tourism has emerged, with activists sealing Airbnb key boxes with glue and obstructing access to popular tourist attractions. Video footage shows demonstrators using strong adhesives on key boxes, which hold keys for holiday rentals, leaving tourists potentially stranded. Additionally, red-and-white barrier tape and unofficial warning signs have been placed around volcanic observation points, aiming to deter visitors. Activists are vocal about the adverse effects of mass tourism on local communities, citing rising property prices and a lack of affordable housing. Messages on stickers and graffiti, such as 'Tourists go home' and notices on rental cars, urge travelers to consider their impact on local residents. The protests are occurring alongside record tourist arrivals, with over 400,000 visitors from the UK in the first quarter of 2026. This unrest follows similar actions in other Spanish cities, highlighting a growing movement against short-term holiday rentals and their consequences for local housing markets.
