From the Riviera Village website:
Ghosts and goblins will mix with princesses and super heroes as Riviera Village hosts the annual Halloween Trick or Treat on October 31. Catalina Ave. will be closed to traffic from Ave. I to Palos Verdes Blvd., and the shops will hand out candy and treats from 5 to 9 pm. This event has become a Redondo Beach tradition, attracting thousands of children each year to enjoy Halloween in a safe and fun atmosphere. Make an evening of it, and stop for dinner in one of the new restaurants in the Village. The Village restaurants are packed after all the Trick or Treating, so make your reservations early. It’s a great way to celebrate Halloween and enjoy all that Riviera Village has to offer.
