Online or at the Filoli House.
On line..or at filoli..may want to book tours ahead of time..i called to buy tickets and tours..both for house and grounds..so worth it:)!!
I bought mine on the Filoli website... print them and bring them in with you. But you may also purchase them at the visitors center...
You just need to wait in line. Tickets are $22 for adults.
Tickets are obtained on park grounds at the entrance past the parking lot
