Louisville High School is located at 22300 Mulholland Drive, Woodland Hills CA 91364. When you arrive at the school, tell the guard at the gate you are there for the Our Lady of Malibu Mass in the convent chapel. He will direct you to the chapel. There are only 10 parking spaces right by the chapel, so you may have to park down below and walk up to the chapel. The guard will be able to assist you.
