Explore the mountain after hours with your own personal guides during our Grandfather by Night series! You’ll discover some of the park’s nighttime wonders, watch a stunning sunset (weather permitting) and experience the mountain as never before! The Twilight Hike version will include a hike after sunset to discuss and look for the creatures that are more active after the sun goes down. The group will explore a unique forest ecosystem from top to bottom in search of salamanders, owls, flying squirrels, fireflies and any other creatures they might come across. The Twilight Hike program is not accessible to guests with limited mobility. Participants signed up for this version will need to participate in the hike, as staying behind while the rest of the group hikes is not possible. Advance registration required.
