Gregory Bald is one of two grassy balds maintained in the Smokies. Native grasses, sedges, ferns, and blueberries grow on the summit. Research suggests that large grazing animals—from mastodons and mammoths to bison, elk, and deer—helped keep these high openings from returning to forest. The open ground is part of the destination, not just a break in the trees. This hike suits people who enjoy the work as much as the view; its length, steady climb, and mostly enclosed upper approach make it a poor fit if you want an easy summit stroll.
