Overview
If you’re looking for one of the most iconic Chattanooga attractions with a unique mix of natural beauty, history, and adventure, Ruby Falls absolutely delivers. This family-friendly destination takes you into the heart of Lookout Mountain through a glass-front elevator, revealing a stunning subterranean world of twisting rock formations, colorfully lit passageways, and ultimately, the breathtaking Ruby Falls—America’s tallest and most magnificent underground waterfall. It’s part science, part spectacle, and all-around memorable.
The story of Ruby Falls starts with a twist of fate. In 1928, chemist and cave explorer Leo Lambert was working on reopening the sealed Lookout Mountain Cave system, a deep natural formation that had been closed during railway construction. While drilling an elevator shaft to reach the cave, Lambert’s team stumbled upon a previously unknown cavern 260 feet below the surface. This accidental discovery changed everything.
Leo Lambert decided to explore the new cavern and, crawling through narrow, low-ceilinged passages with a team of spelunkers and a lantern, he came upon a thunderous waterfall cascading from the cave ceiling—hidden from the world for millions of years. He named it Ruby Falls after his wife, Ruby, and set out to turn it into a destination. By 1930, the site opened to the public, and it’s been an awe-inspiring tourist attraction ever since.
Ruby Falls Plan
For our spring break adventure, we decided to stay in Chattanooga—a city that’s equal parts quirky, scenic, and full of surprises. We were looking for something a little different than the usual beach trip, and Chattanooga delivered with its creative blend of natural beauty and offbeat attractions. We explored charming local shops, discovered unique restaurants and coffee spots downtown, and spent time walking along the Tennessee Riverwalk. One of the highlights of our trip was Ruby Falls, which made for the perfect mix of above- and below-ground wonders—all just minutes from our rental home. Pairing it with a visit to Rock City, perched atop Lookout Mountain, with its whimsical rock formations, swinging bridge, and famous “See Seven States” viewpoint, was a perfect day.

Getting There
Location
Ruby Falls is located inside historic Lookout Mountain, just a few minutes from downtown Chattanooga, Tennessee. The full address is 1720 South Scenic Highway, making it easily accessible for anyone visiting the region or pairing it with nearby sights like Rock City or the Tennessee River Gorge.
Best Time to Go
Ruby Falls is open year-round, and since it’s deep underground, the weather outside doesn’t impact the experience inside. Still, spring and fall are particularly great times to visit—the surrounding Lookout Mountain area is ablaze with color, and the views from the Lookout Mountain Tower are spectacular. Weekdays and mornings tend to be less crowded if you’re hoping to avoid large tour groups.

Who Can Go?
This is a guided tour that most people can enjoy, from curious kids to grandparents. However, it’s important to know that the cavern trail has some low ceilings, narrow passages, and uneven surfaces. It’s not wheelchair accessible, and strollers aren’t allowed in the cave. Those with limited mobility or severe claustrophobia might find it challenging.
What You'll See
Once inside the Ruby Falls Cave, your guided tour will lead you past jaw-dropping rock formations, illuminated with artificial lighting that adds a dramatic flair to the ancient stone. You’ll learn about the history of Ruby Falls, the accidental discovery of the cavern, and geological wonders along the way. And then, the moment everyone waits for—the reveal of Ruby Falls, a thundering waterfall plunging 145 feet from the cave ceiling, enhanced by a choreographed light and music show. The colored lights bring the falls to life in a way that’s both magical and mesmerizing.
Once you exit the cave, don’t miss the Lookout Mountain Tower, where you’ll be treated to spectacular views of the Cumberland Plateau and the Tennessee River Gorge.

What to Bring & Wear
Comfort is key! Wear closed-toe shoes with a good grip—remember, you’re walking through a natural wonder inside a cave with occasionally damp and uneven surfaces. Layers are helpful; while the cave is a consistent 60°F (16°C), it might feel chilly after walking in from a warm day. Leave large bags and strollers in the car.
Where to Go
Once you arrive at Ruby Falls, head into the castle-like visitor center. From there, a glass-front elevator will whisk you 260 feet below sea level, dropping you right into the heart of Lookout Mountain. That’s where your guided cave tour begins.
How Long Does it Take?
The cavern trail tour usually takes about 1 hour and 15 minutes from start to finish. That includes time to explore the formations, take photos, and enjoy the waterfall reveal. Factor in extra time for parking, browsing the gift shop, or climbing the Lookout Mountain Tower after your tour.
