Autumn weather has arrived, cooler nights and dewy mornings are taking the place of those hot summer nights. I love the autumn. Even though the nights are cooler the days are still warm. The insects become less bothersome and sunburns start to taper off. Many people celebrate the season with pumpkin spice, everything pumpkin spice. Here at Cave of the Mounds you can enjoy the colorful leaves, swaying grasses, fall flowers, pumpkins, decorations and a HOLLOW-een trick-or-treat experience inside the cave! During October all cave visitors are invited to participate in our HOLLOW-een sugar free trick-or-treat, with or without a costume, during October.
