Rodger's Gardens Newport Beach

The best time to visit Rodger's Gardens to see the fall/Halloween decorations is really the end of September.  They usually open around September 24 and they have such a reputation that crowds come opening day to purchase the decorations.  If you wait until October there is much that you won't get a chance to see because it will be sold.  They really do an amazing job and it is quite unique.  Check out their website to read about the featured artists and creative team that puts this together.    https://www.rogersgardens.com/pages/halloween

Note:  The Christmas section opens on October 8th this year in case you are interested.
