Recreation
Great Smoky Mountains National Park is a hiker's paradise, with over 800 miles of maintained trails ranging from short, leg-stretchers to strenuous treks, with a number of those trails easily accessible from Cosby Campground, including the Appalachian Trail, just three miles away via the Lower Gap Trail.
Hiking is not the only reason for visiting the Smokies: Fishing, picnicking, wildlife viewing and auto touring are popular activities.
Campers can enjoy high-quality backcountry fishing in the cool waters of the countless streams and rivers that snake through the mountains, with trout available in abundance.
Wildlife viewing is a popular pastime, and with around 1,500 bears living in the park, it's not uncommon for visitors to spot one. The park is a sanctuary for a magnificent array of animal and plant life, all of which is protected for future generations to enjoy.
The park also holds one of the best collections of log buildings in the eastern United States. Over 90 historic structures, including houses, barns, outbuildings, churches, schools and grist mills, have been preserved or rehabilitated in the park.
