This pocket-sized guide from National Geographic lists details about hiking in Great Smoky Mountains National Park. It provides an in-depth map of trails, hills, rivers, streams, mountains, lookouts, water falls, common features, and more. It also includes distances and elevation to each hiking trail, making it a great resource for those starting out for the first time. However, it is important to note that not all maps are updated each year, so it is important to check the year before ordering.
