Hiking
The Grotto Falls Trail offers a delightful and unique hiking experience, winding through a rich old-growth forest before reaching its star attraction. You'll follow the Trillium Gap Trail, passing towering eastern hemlock trees and crossing small streams, with the path being mostly wide but occasionally rocky. The highlight is undoubtedly Grotto Falls, a 25-foot waterfall where you can walk directly behind the cascading water, feeling the cool mist and enjoying a truly immersive moment.
Planning your visit means heading to the trailhead via the Roaring Fork Motor Nature Trail, but be aware that this road closes from December to mid-March, requiring a longer approach from the Rainbow Falls Trailhead during winter. Given its popularity, especially during peak season, arriving early is a smart move to ensure you find parking. This easy 2.0-mile (3.2 km) hike, with a modest 266 feet (81 metres) of elevation gain, takes about 55 minutes, making it a fantastic option for beginners or families.
What truly sets this trail apart is the opportunity to walk behind the waterfall, a feature unique among all the waterfalls in Great Smoky Mountains National Park. The cool, misty cove behind Grotto Falls also provides an ideal habitat for salamanders, adding another layer of natural wonder. Beyond the falls, the Trillium Gap Trail continues, offering options to extend your hike to Brushy Mountain or Mount LeConte, and it's even used by llamas to carry supplies to LeConte Lodge.
