Rhododendron Tunnels
Green, creekside trails near Helen where rhododendron arches over the path
The short answer
Walk under a rhododendron tunnel on a warm day and the temperature drops, the light turns green and the creek sound gets louder. Around Helen the thickets grow thickest along streams, where the evergreen shrubs arch over the trail and close in overhead. There's no single marked "tunnel" to find. It's a feature of several creekside trails, and the best ones are listed below.
Rosebay rhododendron blooms mostly in June, with white to pale pink flowers, while Catawba rhododendron blooms in violet-purple from April through June. Because the leaves stay green all year, the tunnels are worth a walk in any season.

When to go
June is the main bloom window for rosebay, and bloom timing shifts a week or two with the spring weather. Weekday mornings are quieter and the light through the leaves is best then. Overcast days make the greens look richer than harsh midday sun.
Outside bloom season, the trails are still worth walking: the leaves are glossy and green in winter, and fall color filters through the thickets in October. For October crowds and peak timing, see our fall color guide.
Tips
Wear shoes with grip
Roots and wet rock are slick under the canopy, especially near the creeks.
Bring water and bug spray
Creek corridors are cool but buggy in summer. Carry water; there's none on the trail.
Start at Unicoi
Unicoi State Park has the easiest access, with lodge parking, a lake loop and a restaurant. See the Unicoi guide.
Know what's accessible
Smith Creek Trail is a natural-surface path. For a paved option, the 0.1-mile Lion's Eye Trail at Anna Ruby Falls is wheelchair accessible; the 0.4-mile main trail has steep sections that aren't.
Pair the trails with nearby stops: the Unicoi Lake Loop is a flat 2.5-mile walk, and the Helen to Unicoi Trail links the park to town. Looking for a place to stay close to the trailheads? See our family cabins guide and the breakfast and brunch picks for after.
