They have 12 courts. I can get one court for free with my alumni ID card. It usually costs $10.00 per court. The courts are about half way between Atherton and Anaheim off Palo Verde. From Palo Verde walk thru the parking lot to the tennis courts. I understand that parking permits are required to park at CSULB. There should be parking available on Palo Verde which is a short walk from the tennis courts.
