Grotto Falls Trail

What Makes Grotto Falls Special

Grotto Falls holds a unique distinction in Great Smoky Mountains National Park: it's 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.

Beyond this unique feature, the trail offers a beautiful journey through old-growth hemlock forest. You'll also have the chance to encounter the famous llamas that carry supplies to LeConte Lodge—they use this very trail for their resupply trips.

Getting There

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 from downtown and follow it to Cherokee Orchard Road, then continue to the one-way Roaring Fork Motor Nature Trail.

Important: Roaring Fork Motor Nature Trail is closed from late November through mid-March due to winter weather. Check current road 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. A parking permit ($5/day or $40/year) is required March through November.

Trail Description

The trail follows the Trillium Gap Trail, named for the trillium wildflowers that bloom abundantly here in spring. The path winds through old-growth eastern hemlock forest—a rare and precious ecosystem worth appreciating.

What You'll Experience

• Mile 0-0.5: Gentle climb through beautiful hemlock forest with filtered light
• Mile 0.5-1.0: Trail becomes rockier, crossing small streams on log bridges
• Mile 1.0-1.3: Steeper section with sounds of the falls growing louder
• Mile 1.3: Grotto Falls appears—the trail passes directly behind the waterfall

Walking Behind the Falls

The experience of walking behind Grotto Falls is 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.

Best Times to Visit

• Spring (April-May): Trillium and other wildflowers are in bloom
• Summer: The cool mist provides relief from heat, but expect crowds
• Fall: Beautiful foliage and fewer crowds after kids return to school
• After rain: The waterfall is more impressive with higher water flow
• Morning: Best light for photography and fewer hikers on the trail

Photography Tips

• Morning light filtering through the hemlocks creates ethereal conditions
• Bring a lens cloth—spray from the falls can coat your lens
• Protect your camera when walking behind the falls
• A slow shutter speed (1/4 second or longer) creates silky water effects
• Photograph the trail passing behind the falls for a unique perspective

What to Bring

• Water and snacks
• Waterproof jacket or poncho (you may get sprayed)
• Sturdy hiking shoes with good tread (rocks are slippery)
• Camera with lens protection
• Layers (temperatures are cooler in the hemlock forest)
• Insect repellent in summer months

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're 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.
