Ruby Falls: What to Know Before Going Underground
A guided cave walk 260 feet beneath Lookout Mountain, ending at one of Chattanooga’s most memorable natural attractions.
Is Ruby Falls in Chattanooga Worth Visiting?
Yes—especially if you enjoy caves, waterfalls, unusual natural attractions and Chattanooga history.
The standard Ruby Falls Cave Walk takes visitors 260 feet underground by elevator before following a guided, roughly one-mile round-trip trail through Lookout Mountain to the waterfall.
Ruby Falls is one of Chattanooga’s best-known attractions, and after experiencing it firsthand, I understand the appeal.
The underground setting, cave formations, colorful waterfall light show and unusual history make it unlike anything else I visited in the area.
There is one thing I would want first-time visitors to know before booking: the standard Cave Walk can feel fast-paced.
Our group was large, and I often felt like I needed to keep moving rather than stop and carefully compose photographs.
I am still glad I went, but going in with the right expectations would have helped.
Planning a longer visit? My Chattanooga Weekend Guide connects Ruby Falls with the Incline Railway, railroad history, downtown museums, murals, local food and the Tennessee Riverfront.
What Is Ruby Falls?
Ruby Falls is a guided cave attraction inside Lookout Mountain in Chattanooga, centered around the tallest underground waterfall open to the public in the United States.
The experience combines cave geology, local history and the underground waterfall itself.
Visitors enter through Ruby Falls’ historic mountaintop property, descend into the mountain and follow a paved cavern trail with a guide.
The cave and historic Ruby Falls Castle are listed on the National Register of Historic Places, making this more than simply a waterfall stop.
How Was Ruby Falls Discovered?
Ruby Falls was accidentally discovered by Leo Lambert in 1928 while crews were excavating an elevator shaft through Lookout Mountain.
Lambert’s original goal was to create access to Lookout Mountain Cave.
During excavation, workers reached a depth of 260 feet and uncovered a narrow opening in the limestone.
Lambert and a small exploration party entered the newly discovered passage and eventually found an underground waterfall.
He named the waterfall Ruby Falls after his wife, Ruby Losey Lambert.
That accidental discovery ultimately became the attraction visitors explore today.
What Happens on the Ruby Falls Cave Walk?
The standard Cave Walk is a timed-entry, guided express tour that takes visitors through the cavern to Ruby Falls in a large-group format.
The experience begins with a glass-front elevator ride descending approximately 260 feet into Lookout Mountain.
Once underground, you follow the cavern trail past natural formations while learning about the cave’s discovery, geology and history.
The standard Cave Walk is approximately one mile round trip and usually lasts about 1 hour and 20 minutes, depending on the date, group and conditions.
There are several small sets of stairs and uneven areas along the trail, and guests need to be comfortable standing, walking and keeping pace with the group for up to about 90 minutes.
What Is It Like When You Reach Ruby Falls?
The waterfall chamber is the dramatic finale of the Cave Walk.
After traveling through the narrower cavern passages, the space opens around the waterfall and a synchronized lighting presentation illuminates the falling water and surrounding rock.
For me, this was easily the visual highlight of the tour.
The combination of the dark cavern, rushing water and changing light makes the waterfall feel even more dramatic in person.
It is also the point where nearly everyone wants a photograph, so having your phone or camera ready before entering the chamber helps.
Does the Ruby Falls Tour Feel Rushed?
My standard Cave Walk did feel rushed, particularly when I wanted to stop for photographs.
Our group was large, and the narrow passageways meant everyone needed to keep moving.
I sometimes felt nudged forward by the flow of people behind me before I had finished looking at a formation or composing a photo.
The pacing makes more sense when you understand that Ruby Falls describes the standard Cave Walk as an express walk in a large-group format.
Guests are expected to maintain the pace of the group.
If you prefer a slower experience, Ruby Falls currently offers specialty tours on select days.
The Gentle Walking Tour, for example, uses the same cavern route at a gentler pace, includes opportunities to rest and provides additional time at the waterfall. It is limited to guests age 12 and older.
I would consider one of those slower specialty options on a future visit if photography and having more time to absorb the cave were my priorities.
Can You Take Photos Inside Ruby Falls?
Yes. Photography is allowed inside Ruby Falls, and the attraction currently permits flash photography in the cave.
My biggest advice is to work quickly.
On the standard Cave Walk, you may not have time to stop repeatedly and experiment with multiple compositions.

How Much Does Ruby Falls Cost?
As of September 30, 2026, standard Cave Walk tickets are $29.95 for adults, $28.95 for seniors age 65 and older, and $19.95 for children ages 4–12.

Ruby Falls also offers specialty cave experiences at different price points.
Check the official Ruby Falls ticket page for current availability and pricing.
Do You Need to Buy Ruby Falls Tickets in Advance?
Yes. Ruby Falls uses timed-entry tickets, and the attraction recommends purchasing online several days in advance because popular time slots sell out.
Tickets are currently sold online rather than through a standard walk-up ticket window at the attraction.
If Ruby Falls is an important part of your Chattanooga itinerary, I would book it before finalizing nearby activities rather than assuming you can simply arrive at whatever time works that day.
What Should You Know About Walking, Accessibility and Strollers?
If mobility is a concern, contact Ruby Falls Guest Services before purchasing tickets to discuss current options.
What Is the Temperature Inside Ruby Falls?
The cave stays around 60°F year-round.
That can feel refreshingly cool during a Tennessee summer and noticeably chilly if you are dressed for warm outdoor temperatures.
A light layer is useful if you tend to get cold.
How Much Time Should You Allow at Ruby Falls?
Most visitors should allow about two to three hours for Ruby Falls as a whole.
The standard Cave Walk itself usually takes about 1 hour and 20 minutes, but you may also want time for check-in, scenic overlooks, the gift shop, the historic castle and food at Castle Café.
If you are combining Ruby Falls with another Lookout Mountain attraction, avoid scheduling your next reservation too tightly after the cave tour.
Is Parking Free at Ruby Falls?
Yes. Complimentary parking is currently available at Ruby Falls.
The property also provides parking for buses and RVs, along with designated accessible spaces for guests with valid disability parking permits.

What Else Can You Do at Ruby Falls?
The cave is the main attraction, but Ruby Falls includes more than the underground tour.
Admission includes access to scenic viewpoints overlooking the Tennessee River and Cumberland Plateau.
The historic Lookout Mountain Tower also provides elevated views, although its decks are accessed by stairs.
Castle Café serves meals, snacks, coffee and beverages in the historic limestone castle, and you do not need cave admission simply to eat at the café.
Ruby Falls also operates the seasonal High Point ZIP Adventure for travelers looking to add another activity on Lookout Mountain.
What Else Can You Do on Lookout Mountain?
Ruby Falls works especially well as part of a larger Lookout Mountain day.
Ruby Falls FAQ

Is Ruby Falls Worth Visiting?
Ruby Falls was worth visiting for me despite feeling rushed during the standard Cave Walk.
The cave formations, history and waterfall create an experience that is genuinely different from Chattanooga’s above-ground attractions.
Seeing the waterfall deep inside Lookout Mountain was memorable enough that I would still recommend the attraction—with one important qualification.
If you are someone who likes to move slowly, study geological details or spend significant time composing photographs, understand that the regular Cave Walk is intentionally an express group experience.
Consider one of Ruby Falls’ slower specialty tours if the schedule and age requirements work for you.
If your priority is simply seeing Ruby Falls and experiencing the cave for the first time, the standard Cave Walk does exactly that.
Next step: Check current tour times and purchase timed-entry tickets through the official Ruby Falls website before your Chattanooga trip.
