Grotto Falls - 2.6 Miles Round-Trip
Grotto Falls spill 25' over a cavernous rock overhang, or Grotto, into a large pool along Roaring Fork Creek. The Trillium Gap Trail passes through old growth hemlock and mixed hardwood to the fall, and continues behind it en route to Brushy Mountain and Mount Le Conte.
Grotto Falls is the only waterfall in Great Smoky Mountains National Park where you can walk right behind a waterfall on a designated trail. Visitors will enjoy a picturesque setting, swimming, and salamander viewing on the short hike to Grotto Falls.
Hemlock are among the largest and most common trees in the Park. They can grow to 150', have trunks 6' in diameter, and live several hundred years.
Just before reaching the main fall you'll pass a lively cascade and pool suitable for wading (1.23 miles), a good alternative when the Grotto area is overrun with midday crowds.
The main trail continues beside the creek to Grotto Falls (1.3 miles 3,760'), and curls behind it under the protective grotto to the far side. This cool, moist environment is ideal habitat for salamanders, of which there are 30 species in the Park.
The Trillium Gap Trail continues 2.05 miles above the falls to Brushy Mountain, a worthwhile extension for those with time. Brushy Mountain, a heath bald, is celebrated for its spectacular views and rhododendron, laurel, and sand myrtle blooms.

- Lungless salamanders breathe - or exchange oxygen and carbon dioxide - through blood vessels in their skin and linings of their mouths and throats. Salamanders are found in just about every ecosystem and micro-climate throughout the park, but are most commonly found in dark moist areas - like the base of Grotto Falls.
- Great Smoky Mountain National Park estimates there are 800 acres of old-growth hemlock in the Park. Much of this population is threatened by the woolly adelgid, an invasive insect that feeds on sap at the base of hemlock needles, which ultimately disrupts nutrient flow and causes needles to drop. Without needles the tree starves to death, usually within three to five years of infestation. Hemlock forests along the Trillium Gap Trail and Grotto Falls area are currently intact.
- Enjoy waterfalls from a safe distance, and be mindful of slippery surfaces in the vicinity. Do not attempt to climb the falls. Deaths have occurred at numerous falls throughout the Park.
