In Lanzarote, residents have staged protests against mass tourism by gluing shut Airbnb key boxes, which are used for key access to holiday rentals. This disruptive action, along with blocking access to popular tourist spots, aims to highlight the adverse effects of tourism on local communities, particularly rising housing costs and displacement. Activists have been seen applying strong adhesives to key boxes and placing unofficial warning signs around volcanic viewpoints, discouraging visitors. They also attached stickers to rental properties with messages like "Your tourism kills our land" and left notes on rental cars warning tourists of their contribution to local displacement. Protests come as Lanzarote experiences record visitor numbers, with over 400,000 tourists arriving from the UK in early 2026. Residents' groups across Spain are increasingly concerned about the impact of short-term rentals on housing availability, echoing similar protests seen in cities like Granada and during last summer's demonstrations across Spain against mass tourism.
