The Smokies High Peaks Loop is arguably one of the most epic undertakings in Southern Appalachia. It visits Newfound Gap, Alum Cave, Mount LeConte, Charlies Bunion, and several others. It's an all-day adventure loaded with big views — perfect for experienced trail and ultra runners looking for a challenge. If hiking is more your style, it's a great 2-3 day loop with camping at Mount LeConte and Ice Spring Shelter on the AT.
