I LOOOVVVEEE this trail. I'm hoping to do it again soon because it is such a beautiful area.
Cloudland Canyon is directly south of Chattanooga TN and is a great day trip if you're visiting the area.
There is a $5 per vehicle parking fee which is more than reasonable if you plan on spending the day here.
The alltrails linked below is for both Hemlock and Cherokee Falls which I highly recommend doing the full thing if you have time.
Both waterfalls are great for swimming and I really enjoyed Hemlock because you can scramble up and go behind it!
There are also great views of the canyon near the parking area and a big picnic area to enjoy lunch before or after your hike!
