The Recreation, IntraMural and Athletic Complex (RIMAC) is the cornerstone of UC San Diego's sports facilities. This nearly-200,000-square-foot facility is located just south of the 12-acre North Campus Recreation Area Field on the northwest corner of campus.

LionTree Arena, the Triton athletic program's centerpiece facility completed its first significant renovation in its nearly 24-year existence in September of 2018. The project modernized the arena, improves training and competition facilities for Triton student-athletes and provides fans with a first-class live event experience.
