Great Smoky Mountains: Alum Cave & Laurel Falls
Great Smoky Mountains National Park begins 30 miles southeast of Knoxville — close enough for a full active day with time for two of the park's best trails. The Alum Cave Trail to Alum Cave Bluffs is the most geologically distinctive hike in the Smokies: a 4.4-mile round trip through old-growth forest, across a log bridge over Styx Branch, through a dramatic arch formation called Arch Rock, and out onto the open face of the bluffs themselves — a massive concave overhang of Anakeesta slate with sulfur-tinged seeps and views down the Little Pigeon River drainage. Laurel Falls in the afternoon is the most popular trail in the park for good reason: a paved 2.6-mile round trip through second-growth pine and laurel forest to the largest free-falling waterfall in Great Smoky Mountains NP. The Newfound Gap Road scenic drive back through the park closes a complete day in the Smokies.
