Follow the signs for the International-Scenic Highway to Rosarito (for about six miles). Take the "Playas" exit. Go left at the first traffic light, then another left at the next traffic light (after passing Kentucky Fried Chicken and a big shopping plaza on your left hand side). At the forth stop sign, take a left (there is a drug store on the left hand corner and a police station on the far right hand corner). Stay on that road under the underpass and all the way up the hill until you get to the guard station at the entrance to the campus. The retreat house is at the very top of the hill. The guard will point the way.
