What creatures roam the wooded areas at the Preserve? You’ll be able to find out, by taking the Creepy Creatures Halloween Hike. A Preserve naturalist will lead you on a non-scary, free, family friendly hike along Powder Canyon's lovely trails to look and listen for nocturnal animals. We'll discuss owls, snakes, and spiders. You may come in costume but be sure you can still hike with it on. This is a short ( 1.7 mile) evening hike that is sure to be a scream! No dogs.
