About Grotto Falls

Grotto Falls ranks among the most unique waterfall hikes near Gatlinburg, featuring the only cascade in the Great Smoky Mountains that lets you walk directly behind the falling water. The 2.6-mile round-trip trek follows the Trillium Gap Trail through old-growth forest, climbing steadily but manageably to reach the 25-foot waterfall.

The trail itself showcases classic Smoky Mountain terrain, with dense forest canopy providing shade during summer months. Spring hikers are treated to abundant wildflower displays, particularly in May when trillium and violets carpet the forest floor. The consistent uphill grade makes this a moderate hike - challenging enough to feel rewarding but doable for most visitors who pace themselves.

At the falls, cool mist offers welcome relief after the climb. A shallow pool at the base invites careful wading (though rocks can be slippery), while large boulders around the falls provide natural seating for picnics or photography. The cave-like space behind the waterfall creates a unique perspective that's especially popular with photographers.

Important tips: Arrive early, particularly during peak season (June-October), as the parking lot fills quickly. The access road (Roaring Fork Motor Nature Trail) is one-way and closes during winter months. There's no cell service in the area, so download maps beforehand. Wear sturdy shoes with good traction - the trail can be muddy and rocks near the falls are often wet.

Free to access with park admission. The trail typically takes 2-3 hours round-trip for most hikers. Bring water and snacks, as there are no facilities along the trail.

Don't Miss

Walk Behind the Waterfall

This is the only spot in the entire Smokies where you can walk behind a waterfall. The trail literally passes behind the 25-foot cascade, giving you incredible photo ops and a cooling mist on hot days.

Swimming Hole at the Base

The pool below the falls is deep enough for swimming and wading. Kids love splashing around while parents relax on the surrounding rocks. The water stays pretty chilly even in summer.

Wildflower Displays in Spring

May is absolutely gorgeous along this trail with trillium, violets, and stitchwort blooming throughout the forest. The wildflowers are some of the best we've seen in the park.

Moderate Challenge Level

The steady uphill climb makes you work for it without being too brutal. Most families with school-age kids handle it fine with water breaks, and the downhill return feels like a reward.

Cool Forest Canopy

The entire hike stays shaded under thick forest canopy, making it comfortable even on hot summer days. The temperature drops noticeably as you approach the falls in the cove.
