excellent hike. beautiful scenery. the waterfall was awesome. there is a rock ledge to the left just before the falls that you can climb and walk to the top of the falls for a great view. then you can climb straight up the hill on the left side of the falls to get back to the trail instead of climbing back down the rock ledge.
if you do this trail on a weekend, you might want to consider driving to the backside trail to the falls. it is about a 3 mile one way hike to the trails but this will save you a ton of driving time. the drive is longer but the traffic is horrible in cades cove on the weekends. if you dont mind taking about 4 hours to drive 11 miles, then go ahead and enter through cades cove loop.
here are the directions to the backside trail. For backside of Abrams, you will do an end around the park. This will add some mileage to your hike as well. Candidly, it will take you awhile to make the drive, but the views on this drive are very special on the route. coming from Gatlinburg or pigeon forge, go west on Wears Valley Road or Laurel Creek to get to Towsend, take 321 North out of townsend toward Maryville. This parallels the Little River and just prior to getting to Walland you will see signs for The "Foothills Parkway". It is only 18 miles over the parkway. You will come to a t-intersection at Chilhowee
Lake. Take a left and an another immediate left on Happy Valley Road. This Road dead ends at the ranger station. Take Little Bottoms Trail to Abrams Falls trail. As you return, and if you have time cut over on Hannah Mountain
trail to Rabbit Creek Trail to make this a loop route. When you get back to the car, if you have time, you want to stop on the Foothills Parkway at look rock. This trail to the tower is paved. It is just 1/2 mile, steep, but the
tower view is incredible.
