Docent Naturalists Jan Hintermeister, Vivian Neou, Ray Curiel, and Sarah Schoen will be your traveling companions on this leisurely-paced hike through varied habitats of the Bald Mountain and Mt. Umunhum trails. Starting from the Bald Mountain Parking Area we'll hike the Bald Mountain and lower Mt. Umunhum trails. Then we'll carpool/caravan to the Mt. Umunhum summit for further exploration. Although the focus is on butterflies, you'll see many other plant and animal species on the shoulders and summit of this iconic peak. Bring a lunch for a short break, and binoculars if you have them.
