This weekend belongs to the creatures of the night. Explore Nighttime Hoots and Howls in several Portland parks. Learn about spiders (and hold a tarantula!) during the day at Tryon Creek—and then go prowling for nocturnal creatures during an evening hike that night. And bring some nighttime thrills to your own backyard by learning how to build your very own bat house in a family-friendly workshop. And there are plenty of pumpkin patches and corn maizes to explore. Try Kruger’s Harvest Hoe-Down this weekend.
