Yes. UCSD has:
RIMAC, which is the largest gym on campus. It has a weight room, basketball courts, treadmills and about 8 racquetball courts inside it.
Main Gym: a small weight room as well as a basketball courts inside and out, and a pool.
Canyonview Pool: two pools and a small weight room. Not sure if one is olympic sized or not, but it is pretty big. This is usually where waterpolo and swim meets against other schools happen
