Club Union de Excursionistas was found in Belgrano District, Buenos Aires on February 1, 1910. The name was changed to the current one – Club Atletico Excursionistas (CA Excursionistas) in 1920.

The glory days of the club are deep in the past: 10 seasons in Primera Division from 1925 to 1934. It should be mentioned this is old amateur Primera of Argentina, recognized by FIFA. It was much bigger league than today’s Primera – 36 club participated in 1928 and 1930. Our heroes were not big success, usually finishing in the bottom half. Their best year was 1931, when they finished 5th in the 16 club league. But in 1931 18 clubs left Primera to organize their own professional league – Excursionistas finished high, but among the remaining smaller clubs. Until 1934 there were two concurrent leagues, the amateur still the legal one. Once the professionals became legal, they became the Primera Division and Excursionistas plummeted to their contemporary existence in the 4th Division (Primera C Metropolitana). In their entire history only one player of notice played for the club – Rene Houseman (in the Argentine squad for World Cup 1974 and World Cup 1978) – he made his name in Huracan, but ended his long career in Excursio.

Rene Houseman – Argentine champion with Huracan (this is a photo of those days), played 15 minutes as a substitute in the World final 1978, played for River Plate, Colo Colo (Chile), Amazulu (South Africa), and Independiente before joining Excursionistas in 1985.
In 2006 it was rumoured that Maradona was going to play for Excursionistas, but nothing happened.
