The countdown is on! Get your best costumes out- whether it is “sick-seven”, your K POP Demon Hunters outfit or your best MARVEL hero. Our neighborhoods are filled with fabulous events to celebrate the holiday.
One of our personal favorite events is CARVED at Descanso gardens. The botanical gardens transform into a luminous pumpkin wonderland: thousands of jack-o’lanterns, hand-carved gourds, light displays, ghosts, and pathways through the gardens. Wear comfortable shoes, feel free to keep littles in a stroller and hot cocoa is so much fun! This adventure takes about an hour of your time and is worth the Halloween excitement.
