Twilight is a magical time. Join Metro naturalist Ashley Conley on a stealthy dusk hike to search for wildlife in the park. Magnificent vistas from atop the mountain will also give us a chance to spot the moon and bright planets in the summer sky. Bring binoculars or borrow a pair on site. Suitable for ages 8 and older (children must be accompanied by a registered adult). No pets allowed. $10 per person. Advance registration recommended; call Tualatin Hills Park & Recreation District at 503-629-6350.
