This is a nice 17 mile loop up to Gregory Bald from Twenty Mile Ranger Station and back. It’s virtually all uphill to the bald and all downhill coming back. We camped at campsite 92 on the way up and campsite 95 on the way down. We encountered 3 bears, but they were in the distance and scattered pretty quickly when the heard us. Despite gorgeous weather, we only saw about 20 people, most of them on the bald. The bald is the highlight of this hike with 360 degree views of TN and NC and a nice overlook on to Cades Cove below. There are several creek crossings on this hike, so plenty of water sources. Depending on water levels, you may want to bring water shoes for some of the crossings.
