The Greater Eagle River Tennis Association has been in existence as the Eagle River Tennis Club since the 1980s, organized by a group of Eagle River tennis enthusiasts. When the City of Eagle River and Vilas County decided they could not afford to maintain the courts, GERTA came into existence. Ranging from 70 to 100 members each year. GERTA is concerned with maintaining safe, playable courts for its membership and the public. GERTA offers a variety of ‘leagues’, tournaments and events to promote tennis in Eagle River and the surrounding area. A Youth Tennis Camp is held every year the week after the Northland Pines School District ends school. Adult lessons are available usually beginning in June and continuing for six weeks.
