Cumberland Falls State Resort Park
Cumberland Falls State Resort Park: Kentucky’s Moonbow Wonder
Deep in the forested hills of southeastern Kentucky, the Cumberland River plunges 68 feet over a massive sandstone ledge — creating a 125-foot-wide curtain of thundering whitewater that earned Cumberland Falls the nickname “Niagara of the South.” But this waterfall offers something Niagara cannot: on clear nights around the full moon, the mist rising from Cumberland Falls produces a moonbow — a lunar rainbow visible to the naked eye.
Cumberland Falls is one of only a handful of places on Earth where moonbows can be reliably observed, and the only place in the Western Hemisphere where this phenomenon occurs regularly. Spanning 1,657 acres within the Daniel Boone National Forest, the park combines this natural wonder with a historic lodge, 17 miles of hiking trails, and rafting on the wild Cumberland River.

The Moonbow
A moonbow (or lunar rainbow) is exactly what it sounds like: a rainbow created by moonlight instead of sunlight. The phenomenon occurs when the mist from Cumberland Falls refracts moonlight on clear nights around the full moon, creating an ethereal arc of light that appears white to the naked eye — though long-exposure photographs reveal its true colors.

|---|---|
| Best Viewing | 1-2 nights before and after full moon |
| Best Hours | Dusk to midnight (moon low in sky) |
| Visibility | Requires clear skies and sufficient water flow |

The main waterfall is accessible via a short, paved trail from the DuPont Lodge — making it one of the most easily accessible major waterfalls in the Southeast. At 68 feet tall and 125 feet wide, it’s the largest waterfall south of Niagara Falls by volume, and the river below is designated a Kentucky Wild River.

Frequently Asked Questions
What is a moonbow and when can I see one at Cumberland Falls?
A moonbow is a rainbow created by moonlight refracting through waterfall mist. At Cumberland Falls, moonbows are visible on clear nights around the full moon, typically 1-2 nights before and after. The best viewing hours are between dusk and midnight when the moon is low in the sky. The moonbow appears white to the naked eye but shows full colors in long-exposure photographs. Check the park’s official moonbow schedule before planning your trip.
Is Cumberland Falls really the only place in the Western Hemisphere with a moonbow?
Cumberland Falls is one of only two locations in the Western Hemisphere where a moonbow can be regularly observed. The other well-known moonbow location in the world is Victoria Falls on the border of Zambia and Zimbabwe. The specific combination of waterfall width, mist volume, and viewing angle at Cumberland Falls makes it ideal for this rare phenomenon.
Can you swim at Cumberland Falls?
Swimming in the Cumberland River near the falls is prohibited due to dangerous currents and undertow. However, the park has an Olympic-size swimming pool open Memorial Day through Labor Day. Pool admission is free for lodge and cottage guests; day visitors pay $4 for adults and $3 for children.
How big is Cumberland Falls compared to Niagara Falls?
Cumberland Falls is 68 feet tall and 125 feet wide, earning it the nickname “Niagara of the South.” While significantly smaller than Niagara Falls (which is 167 feet tall and over 3,000 feet wide), Cumberland Falls is the largest waterfall south of Niagara by volume and offers something Niagara cannot — a reliable moonbow.
