Grotto Falls - Great Smoky Mountains National Park
The hike up to Grotto Falls is not that steep and is about 2.6 miles but it is over rocky and tree root laden pathways that create quite an obstical course if you aren't paying attention.
The most distinctive feature about Grotto Falls is that it's the only waterfall in Great Smoky Mountains National Park that a person can actually walk behind. The 25-foot high waterfall offers a cool, shady, and moist retreat for hikers in the summer. This same environment also provides an ideal habitat for salamanders as well. As you walk behind the falls you can hear and feel the thunderous power of the water plunging into the pool in front of you. Watch your step here - especially in the winter - the area around the falls is always wet and slick.
