Purchase Knob is located in the Great Smoky Mountains National Park and is about thirteen miles from the Inn. It took me about thirty minutes to get there and the hiking time is about one and a half to two hours. The hike starts on Purchase Road at the gate, park here even if the gate is open or you could get locked behind the gate. Then its a gradual climb on a gravel road. The road will split, take the road to the left, there will be a sign for Ferguson Cabin and Cataloochee Divide Trail follow that up. To the right, a grassy path will lead you to Purchase Knob this is a steeper climb but worth it. The round trip distance is about two and a half miles. The Smokies, Pisgah National Forest and the Black Mountains can all be viewed . On the way down there is a short trail to Ferguson Cabin which was built in the 1870's and was inhabited until 1902 it is open and the inside and outside can both be seen. Purchase Knob is great place to spend the day. There are other trails that can be joined for a longer hike and it doesn't seem to get as crowded as some other hikes.
