Having won the Campeonato de Aficionados (national amateur cup) in 1973,[4] their most successful period was in the 1980s when they were members of the Tercera División across the decade. In 1980–81 and 1982–83, their 6th-place league finish earned entry to the following season's Copa del Rey. Since then they have mostly played at provincial level, being promoted as the Gipuzkoa league winners four times (1993, 2001, 2012, 2016)[5] but being relegated back down immediately on each occasion. They went up again in 2020,[2] and also played in the 2020–21 Copa del Rey, losing to top-tier regulars Getafe CF only via a penalty in stoppage time.[6]
The club has youth sections and a women's team (who finished 6th in Spain in 1994–95), and also competes in several other sports.
