Groundhopping is a hobby that involves attending matches at as many different stadiums or grounds as possible. Participants are known as groundhoppers, hoppers or travellers. Largely a football-related pastime, groundhopping probably found its origin in football in the 1970s in England. From the late 1980s fans in Germany started groundhopping as well. Currently it is especially popular in the United Kingdom, Germany, the Netherlands and Belgium.
