Our annual Howl-O-Ween event returns to Hartley Nature Center on the morning of October 26, 2019 with an all outdoor format! Come dressed in costume and enjoy exploring the trails and outdoor campus near the nature center. Be sure to dress for the weather since this year’s event will again be ENTIRELY OUTDOORS, no matter the weather. There will be games, a critter trail, and of course treats. Howl-O-Ween is intended for children ages 0 to 8 years old, with an adult, and is FREE for HNC members ($15 for non-member households). This year there is one open-house style session from 9 am – noon. Pre-registration is required by calling the nature center at 218-724-6735. Make sure to register early, as this event will fill up.
