Halloween lovers young and old will light up at Pumpkin Nights, a glowing spectacle of more than 3,000 hand-carved pumpkins. As you stroll along a pumpkin-lined pathway, stop by the Pumpkin Passage (but watch out for pirates!), enjoy a mariachi band and sugar skulls in the Día de los Muertos area and take a trip underwater to the Great Pumpkin Reef, filled with bubbles, mermaids and coral. Activities like games and movie screenings will be available to the whole family, and food and drinks will be sold. 1273 High Street in Auburn, www.pumpkinnights.com.
