Regularly ranked among the best aquariums in the country, Ripley's Aquarium of the Smokies holds 10,000-plus animals in 1.4 million gallons in the middle of downtown Gatlinburg. The signature is Shark Lagoon's 340-foot underwater tunnel — North America's longest — where a moving glidepath carries you beneath sand tigers, sawfish, and green sea turtles. Penguin Playhouse lets kids pop up inside the colony through crawl-tunnels and domes; Stingray Bay adds touch encounters and dive shows; and galleries run from a living coral reef to jellies and the Amazon. Fully indoor, open 365 days with long hours, it's the corridor's premier rainy-day ticket — and genuinely world-class on any day.
When Ripley's built its flagship aquarium at the foot of the Smokies in 2000, the bet looked odd — a marine palace in the mountains — and it has paid off for twenty-five years: consistent national top-five rankings, the corridor's most reliable five-star reviews, and lines on rainy days that prove the point. The building holds more than 10,000 animals across 350 species in 1.4 million gallons of exhibits, laid out as a loop that builds to the showstopper.
That showstopper is Shark Lagoon
A 750,000-gallon habitat crossed by a 340-foot acrylic tunnel — the longest underwater tunnel on the continent — with a slow glidepath underfoot, so you drift while sand tiger and nurse sharks, a smalltooth sawfish, giant groupers, and green sea turtles pass overhead close enough to count gill slits. Penguin Playhouse is the family's other anchor: African penguins porpoising past windows while kids crawl interior tunnels to pop-up domes inside the colony itself.
Stingray Bay runs supervised touch sessions and scheduled dive presentations; Touch a Ray and horseshoe-crab stations add more hands-on; and the gallery loop covers a living coral reef, Indo-Pacific tangs and clowns, seahorses, lionfish, moon jellies under shifting light, piranhas and poison dart frogs in the Amazon wing. Daily programs — feedings, dive shows, the mermaid performances kids adore — rotate through the schedule year-round.
Logistics are friendly
Downtown Gatlinburg location (Parkway light #5, garages nearby), open 365 days with long hours, fully indoor and stroller-easy, two to three hours self-paced. Timed tickets tame the peak days — book ahead for rainy afternoons, summer, and holiday weeks, when half the corridor funnels here. Combo passes with other Ripley's Gatlinburg attractions suit multi-stop days, and annual passes pay off for repeat regional trips.
What to expect
The experience
A top-ranked indoor aquarium — the 340-foot glidepath shark tunnel, Penguin Playhouse crawl-tunnels, stingray touch bay, dive and mermaid shows, and gallery loops from coral reef to Amazon. Open 365 days.
Best time
Opening hour or evening on clear days; it's the whole corridor's rainy-day plan, so sunny afternoons run quietest. Book timed entry for wet days and holidays.
How long
Two to three hours self-paced, plus show times if you plan around the schedule.
Tips
Check the daily program board on arrival and anchor your loop to a dive show or penguin feeding. Ride the shark tunnel glidepath twice — the cast overhead changes. Combo tickets with other Ripley's Gatlinburg stops save on multi-attraction days. Garages beat street parking downtown.

Good questions
Is it really one of the best aquariums in the country?+
It ranks in national top-five lists year after year — the shark tunnel, penguin habitat, and program schedule outclass aquariums in cities ten times Gatlinburg's size.
What's the shark tunnel like?+
340 feet of acrylic under a 750,000-gallon lagoon with a slow moving glidepath — sand tiger sharks, sawfish, groupers, and sea turtles cruise inches overhead. It's the longest underwater tunnel in North America.
Can kids touch anything?+
Yes — supervised stingray and horseshoe-crab touch stations run daily, and Penguin Playhouse's crawl-tunnels put kids inside the colony behind glass.
How long does a visit take?+
Two to three hours at a family pace; the daily shows (dive feedings, mermaids) can stretch it pleasantly.
Is it open when everything else closes?+
365 days a year with long hours — it's the corridor's bad-weather and holiday constant.
