Chasing the Mist: Hiking to Rainbow Falls in the Great Smoky Mountains
An energetic day hike to a mist-shrouded cascade where rainbows are earned, not given.
You hit the trail when the forest still smells of overnight rain and soil — that cool, green smell that seems to soften even the rugged climbs ahead. The path to Rainbow Falls in Great Smoky Mountains National Park is mercifully direct at first: a narrow ribbon folding through hardwoods, laurel and rhododendron pressing in like green curtains. Every step that climbs toward the roar grows louder until the trees open and the world becomes spray and stone. The waterfall itself announces itself before you see it — a white column throwing up a constant, glittering veil. When the sun catches the mist just right, a thin arc of color hangs above the pool, giving the cascade its name.
Trail Wisdom
Start early
Begin before 9 a.m. to avoid crowds and get the best light for rainbows; afternoons bring more visitors and spray-driven glare.
Wear grippy footwear
Trail surfaces are rocky and root-strewn; trail runners or hiking boots with good tread reduce slips.
Pack extra water
Expect a steady climb and limited shade in sections; bring at least 2 liters for a day hike in warm weather.
Protect electronics from spray
The mist near the falls can soak cameras and phones—use a dry bag or weather cover.

Conservation Note
Stick to trails, pack out waste, and follow bear-aware practices; the park manages visitor impact through education and seasonal trail maintenance.
The Great Smoky Mountains area preserves both Cherokee ancestral lands and relics of Appalachian settler life; the park was established in the 1930s to protect this landscape from logging.
