What Makes Grotto Falls Special

Grotto Falls holds a unique distinction in Great Smoky Mountains National Park: it is the only waterfall where you can actually walk behind the cascade. The trail passes directly behind the 25-foot falls through a recessed grotto in the rock, allowing you to experience the waterfall from an angle most visitors never get to see at other waterfalls.

Beyond this unique feature, the trail offers a beautiful journey through one of the park's remaining old-growth hemlock forests. The eastern hemlocks create a cool, cathedral-like atmosphere even on the warmest summer days. While many hemlock groves in the Smokies have been affected by the hemlock woolly adelgid, treatment efforts along this trail have preserved much of the forest.

The hike to Grotto Falls also offers something no other waterfall trail in the park can match: the chance to encounter llamas! These working animals carry supplies to LeConte Lodge and use this very trail for their resupply trips. Seeing a llama train on a Smoky Mountain hiking trail is a uniquely delightful experience that guests staying at our hiking-friendly cabins often talk about.

The trail to Grotto Falls is accessed via the Roaring Fork Motor Nature Trail, which is itself a scenic experience. Consider driving the full loop before or after your hike to see historic cabins, rushing streams, and beautiful mountain scenery.

Llama Sightings on the Trail

One of the most charming aspects of hiking Grotto Falls is the possibility of encountering the famous llamas that supply LeConte Lodge. These gentle animals have been making supply runs since 1987, carrying everything from fresh linens to food supplies up to the mountaintop lodge.

Llama Schedule

Llamas make regular supply runs to LeConte Lodge from spring through fall. Check the LeConte Lodge website for the current schedule. If you encounter them on the trail, step to the downhill side and wait quietly for them to pass.

When you meet the llamas on the trail, follow proper trail etiquette: move to the downhill side, stand quietly, and let them pass. The llama handlers appreciate your cooperation, and the llamas are usually quite calm around hikers who remain still. Many visitors consider a llama encounter the highlight of their hike, so have your camera ready!

Getting There and Parking

The trailhead is located at the Grotto Falls parking area on Roaring Fork Motor Nature Trail. To reach it from Gatlinburg, take Historic Nature Trail (also called Airport Road) from downtown and follow it to Cherokee Orchard Road. Continue past the entrance to the Great Smoky Mountains National Park, and then onto the one-way Roaring Fork Motor Nature Trail.

Seasonal Road Closure

Roaring Fork Motor Nature Trail has occasional seasonal road closings. Check the park website or Sugarlands Visitor Center for current conditions before planning your hike.

Parking is limited to about 20 spaces and fills early on weekends. Consider arriving by 8 AM during peak season (June through October). A parking permit ($5/day or $40/year) is required from March through November. From our cabins near downtown, you can reach the trailhead in about 20 minutes.

Trail Description

The trail follows the historic Trillium Gap Trail, named for the trillium wildflowers that bloom abundantly here from late March through May. The trillium displays are particularly impressive in April, making spring one of the best times to visit. You may also spot lady slippers, violets, and dozens of other wildflower species.

The path winds through old-growth eastern hemlock forest, a rare and precious ecosystem worth appreciating. The massive trees, some hundreds of years old, create a cool, shaded canopy that makes this hike comfortable even on hot summer days.

What You Will Experience

The trail surface is mostly dirt with embedded rocks and exposed roots. Several log footbridges cross small streams. Sturdy hiking shoes or boots with good tread are recommended, especially since rocks near the falls are perpetually damp.

Walking Behind the Falls

The experience of walking behind Grotto Falls is truly magical. The trail literally passes through the grotto behind the cascade, with water flowing in front of you. On sunny days, you might catch rainbows in the mist. The spray can be refreshing on a warm day, or chilly on a cooler one.

Be prepared to get slightly wet as you pass behind the falls. The rocks in this area are perpetually damp and slippery, so watch your footing carefully. Take your time and enjoy this unique perspective. Many visitors pause behind the falls to take photos, but be considerate of others waiting to pass.

What to Bring

Continuing to Mount LeConte

Grotto Falls is located on the Trillium Gap Trail, which continues 5.5 more miles to the summit of Mount LeConte and LeConte Lodge. If you are up for a longer adventure, you can continue past the falls, but be prepared for significantly more strenuous hiking with over 3,000 feet of additional elevation gain.

Most visitors wisely turn around at Grotto Falls, making for a manageable 2.6-mile round trip hike. But knowing you are on the same trail used by the llamas to reach one of the most famous backcountry lodges in America adds an element of adventure to the experience.
