(ii) Geotagging of destinations is widely lamented for fueling overtourism, but now is being used to help travelers with disabilities, aid in wildlife conservation, and showcase forgotten Black history. When tourists upload images or videos to Instagram, TikTok, Facebook, or X (formerly Twitter), they commonly use geotagging, which attaches their GPS coordinates. This allows them to document their travels, but can also trigger a deluge of visitors to heavily geotagged spots, like Arizona’s Horseshoe Bend, which became more littered. On the flip side, geotagging is increasingly being used in positive ways, helping to address environmental and social issues, and even crowding, according to tourism experts. Aiding tourists with disabilities is one of several upsides to geotagging, says Ulrich Gunter, professor of tourism economics at Modul University Vienna in Austria. Google Maps has a function that shows wheelchair-accessible routes through many of the world’s major cities, based on geotagging of accessible ramps, lifts, and car parks. At the same time, tourists can harm a destination by geotagging it, warns Greg Richards, professor of placemaking and events at Tilburg University in the Netherlands. Amsterdam is experiencing a blight dubbed the “TikTok queue,” where tourists swarm the same few geotagged restaurants or cafes trending on social media so they can film similar videos to post online. TikTok queues cause commotion, crowding, and littering, Richards explains. Some venues are so inundated, like Amsterdam’s Fabel Fries restaurant, that they now have two lines, one for regular customers, and another for content creators. Geotagging can also harm natural locations, like South Africa’s Kruger National Park, where poachers tracked endangered animals via social media posts. Such spots which are widely geotagged often suffer “soil erosion, habitat destruction, and depletion of local flora and fauna due to uncontrolled visitor activities,” says Natalia Bayona, executive director at the United Nations World Tourism Organization. Fortunately, geotagging by travelers can have benefits for wilderness destinations, Bayona adds. This technology is being used by tourists to aid citizen science projects, such as wildlife tracking and environmental monitoring. “By sharing the location of various flora and fauna, or reporting instances of littering and pollution, tourists can help local authorities and conservationists better understand ecological trends and challenges,” she says. “This grassroots approach not only empowers travelers by giving them a sense of agency in preserving the destinations they love, but also fosters a deeper connection between tourists and the local environment.”
