Overtourism is congestion or overcrowding from an excess of tourists, resulting in conflicts with locals. The World Tourism Organization defines overtourism as "the impact of tourism on a destination, or parts thereof, that excessively influences perceived quality of life of citizens and/or quality of visitor experiences in a negative way". This definition shows how overtourism can be observed both among locals, who view tourism as a disruptive factor that increasingly burdens daily life, as well as visitors, who may regard high numbers of tourists as a nuisance. Instagram tourism has been implicated as a cause.
