Day 6/7 part 1 of 2 - Arch Rock Going to Alum Cave? Stop on the way and take some pictures at Arch Rock. This stunning rock formation occurs after you cross a brook using a narrow wooden path (so narrow I'm hesitant to even call it a bridge). The rock formation has stairs so you can walk through it, or sit on the steps and take a cute pic. #smokymountains #nature #gatlinburg #hiking
