Although only two miles in length (4 miles round trip), the Great Smoky Mountains National Park trail to Chimney Tops requires strength and caution. Nevertheless, due to the excellent views from this trail, as well as abundant wildflowers, streams and large trees, many feel a hike up to “the chimneys” is well worth the extra effort. Over time, the Chimney Tops trail has become one of the Great Smoky Mountain National Park’s most popular hiking trails.
