Top 9 Challenging Hikes for Experienced Hikers

The classic route up Mount LeConte runs 10 miles round trip on a steep, rocky trail with stairs and bridges. You walk through Arch Rock and under Alum Cave Bluffs, an 80-foot overhanging cliff at mile 2.3, before reaching the summit viewpoints at Cliff Top and Myrtle Point. It is the hike your strongest hikers will talk about all week.

From Newfound Gap, this 8-mile round trip follows the Appalachian Trail through hardwood and high-elevation spruce-fir forest to a rocky outcrop surrounded by steep cliffs. Expect many steep sections with roots and rocks, and a wide panoramic view at the end. Keep a close eye on everyone near the edges, where the drop-offs are real.

At 105 feet, Ramsey Cascades is the tallest waterfall in the park, and you earn it: 8 miles round trip with more than 2,000 feet of climbing over roots and rocks. The trail reopened in November 2024 after a three-year rebuild that added two footlog bridges and more than 600 new steps. The park asks hikers not to climb to the top of the falls.

From Cosby Campground, the Low Gap Trail climbs steeply to the Appalachian Trail, and a ridge walk leads to the rock-and-timber fire lookout the Civilian Conservation Corps built atop Mount Cammerer in 1937 and restored in 1996. The round trip is about 11.1 miles with roughly 3,000 feet of gain, and the lookout's views sweep across the eastern Smokies.

Short but steep: the Chimney Tops Trail gains nearly 1,500 feet in less than 2 miles each way, with no switchbacks on the hardest stretch. Since a 2016 fire, the bare-rock summit is closed for safety, and the trail ends at an observation area that looks across at both rock points. It makes a hard half-day for strong legs.

Gregory Bald is a grassy summit at about 4,900 feet, famous for the flame azaleas that bloom across it in late June. Most hikers climb Gregory Ridge Trail from the end of Forge Creek Road in Cades Cove, 11.4 miles round trip with roughly 3,000 feet of gain. Budget a full day, since reaching the trailhead means driving part of the one-way Cades Cove loop first.

One of the toughest day hikes in the park: 11.7 miles round trip and about 4,100 feet of climbing from Big Creek to the 5,842-foot summit of Mount Sterling. At the top stands a 60-foot fire tower built by the Civilian Conservation Corps in 1935, with long ridge-and-valley views. This remote eastern corner of the park means real solitude.

The longest hike on this list covers 16.2 miles round trip from Newfound Gap, with 2.7 miles on the Appalachian Trail before the Boulevard Trail heads to Mount LeConte. It is high-elevation hiking the whole way, steep in places with roots and rocks, and the park rates it strenuous. Save it for your fittest hikers and a dawn start.

This strenuous trail leaves Baxter Road off US 321 and climbs about 3,500 feet over 7.2 miles, with stream crossings along the way. Its highlights are Albright Grove, a rare stand of old-growth cove hardwood forest with trees more than 200 years old, and the dense rhododendron of Maddron Bald near the top, where the views open up.
