Trick-or-Treat Street October 25 @ 5:00 pm - 8:00 pm While there will be the usual trick or treating around Eureka Springs on Halloween night, you can also take your little boos and ghouls out for a free and family-friendly night of traditional trick-or-treating with participating downtown merchants on Friday, October 25th. Bring your best-carved jack-o-lantern to Basin Park to enter it into the pumpkin carving contest, and include it in the Great Pumpkin lighting ceremony. View classic kids’ Halloween cartoons in the City Auditorium, and check out the amazing Halloween Tree in Basin Park. Plus, enter your kids and/or pets in the costume contest! Presented by Eureka Zombies and members of the Heart of Eureka.
