The shorter and less difficult version of the classic Mt. LeConte hike, taking the Alum Cave Trail just to the bluffs and back is still a worthy adventure any day. With great views and some distinctive features, this is also one of the most popular trails in the area so get there early on weekends. Make sure to bring a jacket in case it rains.
The trail begins on US-441, a few miles west of Newfound Gap and Clingman's Dome road. From the parking area, the trail starts off easy, crossing two bridges over the Walker Camp prong and the Alum Cave creek, then continuing along the latter. At 1.4 miles, the trail climbs up a rock staircase passing through the Arch rock. These steps are steep and slippery and should be climbed with caution using the railing. This can be a bottleneck for thru traffic.
From Arch Rock to Alum Cave Bluffs, the path becomes gradually steeper. Shortly before reaching Alum Cave Bluffs, the trail makes a 90 degree turn North which marks Inspiration Point. This is a good spot to stop and soak in the view, but don't take too long, you're almost there.
While technically it is referred to as a rock shelter, Alum Cave Bluff is definitely not a cave. The giant rock outcropping can accommodate several hundred people. This hike stops here, but if you're up for a longer and more difficult hike, check out Mt. LeConte via Alum Cave Trail for another great hiking option.
