About Alum Cave Trail

Alum Cave Trail ranks among the most popular hiking experiences in the National Park, and for good reason. This 5-mile round-trip trail (or 11 miles if you continue to Mount LeConte's summit) showcases the Smokies' diverse landscapes through a well-maintained path that's challenging enough to feel rewarding.

The trail begins with a gentle one-mile stretch through old-growth forest, crossing several sturdy footbridges over mountain streams. At Arch Rock, the path steepens significantly as it winds through a unique natural tunnel formed by ancient black slate. Inspiration Point appears at mile 1.5, offering expansive views of the surrounding peaks and valleys, especially dramatic during sunrise.

The main attraction, Alum Cave Bluffs, awaits at 2.3 miles. This massive concave cliff face stretches 80 feet high, creating a natural shelter where you'll often feel cool air flowing from the rock face. During winter, impressive icicle formations dangle from the bluff's edge.

Free to access, the trail is open year-round but requires careful planning. Parking fills completely by mid-morning, especially on weekends and during peak fall colors. Arrive before 8 AM to secure a spot. Bring layers - temperatures can vary significantly between the trailhead and higher elevations. The trail can be slippery after rain, and some sections include cable handrails for safety.

For the best experience, allow 3-4 hours for the round trip to Alum Cave Bluffs, or 6-7 hours if continuing to Mount LeConte. Pack water, snacks, and rain gear regardless of the forecast - mountain weather changes quickly.

Don't Miss

Arch Rock

This natural slate archway about a mile up the trail has carved stone steps leading through it. It's like walking through a mountain tunnel that nature made millions of years ago.

Inspiration Point

Around mile 1.5, you'll hit this heath bald with sweeping views of Little Duck Hawk Ridge. It's the first real payoff for your climbing efforts and a great photo spot.

Alum Cave Bluffs

The trail's namesake isn't actually a cave but a massive overhanging cliff face. The dry shelter underneath is perfect for lunch breaks, and the geological formations are incredible.

Mount LeConte Summit

At 6,593 feet, this is the third-highest peak in the Smokies. The summit itself has limited views, but it's an accomplishment just getting there.

Cliff Top

A short 0.2-mile detour from LeConte's summit leads to the best panoramic views in the area. Most hikers skip this, but we think it's the real highlight of the whole trail.

Creek Crossings

The lower section of trail follows mountain streams with crystal-clear water. There are several bridge crossings and spots where you can refill water bottles or cool off.
