It's a short trail of 1.7 miles, although you can make it longer by taking the loop trail (4.6 miles). We were all worn out after our camping weekend, so we opted for the shorter trail.
Twin Arches is an absolutely perfect hike for all hiking levels, as long as one can handle steep steps.
The pay-off is fabulous: great views, lots of rocks for climbing upon, a small cave with a Fat Man's Squeeze, and, of course, the marvel of the arches.
Under the arches, there are lots of great nooks and crannies, including the Fat Man's Squeeze. As a bonus, this area is nice and cool on a hot day!
I love hikes like this with phenomenal views and remarkable natural formations. The rocks are enormous and the arches truly astounding. Once again, I am reminded of how blessed we are to live right smack dab in the middle of all this beauty in East Tennessee.
Big South Fork is less than two hours north of Knoxville. It's kind of tricky to get there, but you'll probably want to go to the Bandy Creek Visitors' Center and start from there. Here are great directions once you figure out where you are.
