5,000 carved pumpkins lining a ¼-mile trail, illuminated at night as an “art show”. With more than 5,000 professionally carved jack o’ lanterns, and well over 100 intricate masterpieces, Jack O’ Lantern Spectacular illuminates a one-third-mile trail in Louisville’s historic Iroquois Park. This year’s theme, “The Four Seasons,” features vignettes set to music highlighting themes from literature, pop culture, history, art, and cinema. Proceeds benefit the Louisville Parks Foundation.
