The most visited national park isn’t found in the desert or along the sea, but instead in the southeast’s tree-covered and ages-old forests of the Appalachian Mountains.
Part of the allure of this national park is its charming, attraction-filled towns — Gatlinburg and Pigeon Forge, Tennessee, and Asheville, North Carolina — all nestled into the heart of the Smokies.
The areas feature Dolly Parton’s Dollywood theme park, an aquarium, a mountain coaster, a sky lift, a space needle, water parks, a theater, breweries and America’s largest mansion, making this park and its surroundings ideal for an all-around vacation.
