The Mirage used to be the center of the world in Las Vegas. If you walked through those front doors in the nineties or early 2000s, you weren't just walking into a casino; you were walking into a jungle that felt oddly, impossibly real. And at the heart of that tropical fever dream sat Siegfried & Roy’s Secret Garden and Dolphin Habitat. It was a place where you could see a white tiger nap behind a glass pane and then, five minutes later, watch a bottlenose dolphin breach in a tank just a few yards away from the slot machines.
But things changed. If you’re looking for tickets right now, you’re out of luck.
The reality of the Secret Garden and Dolphin Habitat is now a mix of nostalgia and corporate transition. In November 2022, the facility closed its doors for good. It wasn’t just a seasonal break. It was the end of an era that defined the "Old New Vegas"—that specific window of time when the city tried to pivot from Sin City to a family-friendly Disney-on-the-Strip.
Why the Mirage Closed the Secret Garden
Hard Rock International bought the Mirage from MGM Resorts, and their vision for the property didn't include a multi-species zoo. They wanted a giant guitar-shaped hotel. They wanted rock and roll. They didn't want the liability or the massive overhead of maintaining a high-tech aquatic filtration system and a sanctuary for apex predators.
It's actually kinda wild when you think about the logistics. Running a dolphin habitat in the middle of the Mojave Desert is an engineering nightmare. You have to keep thousands of gallons of water at precise temperatures while the outside air is hitting 115 degrees.
Beyond the corporate buyout, the "Secret Garden" had been facing increasing pressure from animal welfare groups. Public sentiment regarding captive marine mammals has shifted dramatically since the 1990 opening. Following the deaths of several dolphins over the years—including K2, Maverick, and Bella—activists were calling for the facility to be shuttered long before the Hard Rock deal was even on the table.
Where did the animals go?
People were genuinely worried about the transition. You can’t just drop a captive-born tiger at a local shelter.

The relocation process was massive. Most of the big cats—the famous white tigers, lions, and leopards that Siegfried & Roy spent their lives with—were moved to WildCat Ridge Sanctuary in Oregon. It's a non-profit, accredited sanctuary that doesn't allow public tours, which is basically the retirement every aging Vegas performer dreams of: peace, quiet, and no cameras.
The dolphins had a different path. The Atlantic bottlenose dolphins were relocated to Coral World Ocean Park in the U.S. Virgin Islands. The move happened in phases, starting in early 2023. Experts from the National Aquarium and other marine institutions oversaw the transport to ensure the animals didn't stress out too much during the flight. Yes, they flew on a specialized plane.
The Legacy of Siegfried & Roy on the Strip
Honestly, you can't talk about the Secret Garden and Dolphin Habitat without talking about the guys whose names were on the sign. Siegfried Fischbacher and Roy Horn were more than just magicians. They were the reason the Mirage existed in the first place. Steve Wynn took a massive gamble on them, and they rewarded him by becoming the highest-grossing act in the history of the city.
The Secret Garden was their personal passion project. It wasn't just a side attraction; it was a breeding program. They were obsessed with "saving" the white tiger, though modern conservationists often point out that white tigers aren't a separate species but a genetic mutation that doesn't actually occur in the wild.
Still, for the average tourist in 1995, seeing those cats was a religious experience.
The 2003 on-stage accident involving Roy and a tiger named Montecore effectively ended the show, but the Garden stayed open for nearly twenty more years. It became a sort of living memorial to their career. When Roy passed away in 2020 and Siegfried in 2021, the habitat lost its primary protectors. Without them there to walk the grounds, the heart of the place felt a bit empty.

What it was actually like to visit
If you ever went, you remember the smell first. It was that distinct mix of chlorine and expensive landscaping.
The Dolphin Habitat was the first part you’d hit. It consisted of several interconnected pools. They had a "Trainer for a Day" program that cost a few hundred bucks, where you could put on a wetsuit and get splashed by a dolphin named Duchess. It was one of the few places in Vegas where you could actually get away from the sound of the "ding-ding-ding" of the machines.
Then you’d walk through a gift shop—because Vegas—and out into the Secret Garden. It was lush. They had misting systems everywhere. You’d walk along these shaded paths, and suddenly there’s a black panther.
The Criticisms
It wasn't all sunshine and rainbows. A lot of visitors in the later years started feeling "kinda" uneasy about the enclosures. Compared to modern "open-concept" zoos like the San Diego Zoo Safari Park, the enclosures at the Mirage felt small. They were beautiful, sure, with their faux-rock walls and manicured grass, but they were still essentially gold-plated cages in the backyard of a hotel.
The dolphins, specifically, were a point of contention. The tanks were deep, but they were concrete. Critics argued that the desert sun and the lack of a natural ocean environment were detrimental to their health. The facility maintained that their care was world-class, but the optics got harder to defend every year.
The Mirage Transformation: What’s next?
The Mirage as we knew it is disappearing. The volcano? That's going too. The Secret Garden? Already gutted.

Hard Rock is turning the property into a massive hub for live music and high-end gaming. The area where the lions used to roam is being repurposed. The site is becoming the "Hard Rock Las Vegas," and the skyline is going to be dominated by that 600-foot tall guitar tower.
It marks a total shift in how Vegas markets itself. We're moving away from "themed" resorts (the pyramids, the castles, the jungles) and toward "lifestyle" brands. It's less about the spectacle of a white tiger and more about the spectacle of a residency by a global pop star.
Moving Forward: Where to find animals in Vegas now
If you’re landing at Harry Reid International and you were really hoping to see some wildlife, the Secret Garden and Dolphin Habitat being gone leaves a bit of a hole. But you aren't totally out of options.
- The Flamingo Wildlife Habitat: It’s free. It’s right on the corner of Flamingo and Las Vegas Blvd. You’ve got Chilean flamingos, pelicans, and turtles. It’s not as "grand" as the Secret Garden, but it’s a nice 15-minute breather.
- Shark Reef Aquarium at Mandalay Bay: This is probably the closest thing to the Mirage experience left. It’s a legitimate, AZA-accredited aquarium. They have a tunnel where sharks swim over your head. It’s dark, cool, and actually pretty educational.
- Lion Habitat Ranch: This is off-Strip, located in Henderson. It’s where many of the MGM lions went back in the day. It’s more of a "raw" experience—less glitter, more actual ranch vibes—but it’s the best place to see big cats nearby.
- SeaQuest at Boulevard Mall: Honestly, this one is hit or miss for some, but it's an interactive aquarium if you have kids who need to touch a stingray.
The closure of the Siegfried & Roy’s Secret Garden and Dolphin Habitat was inevitable. It was a 20th-century attraction trying to survive in a 21st-century world. While it's sad to lose a piece of the city's history, the relocation of the animals to sanctuaries and specialized parks is widely considered the best outcome for their well-being.
Actionable Steps for your next Vegas Trip
- Check the status of the Mirage (Hard Rock) before booking. Construction is heavy right now. If you want a quiet pool day, this might not be the spot until the transition is complete.
- Visit the Shark Reef early. If you’re looking for that aquatic fix, go to Mandalay Bay right when they open at 10:00 AM. It gets crowded with strollers by noon.
- Support WildCat Ridge. If you actually cared about the tigers in the Secret Garden, look up the sanctuary in Oregon where they live now. They often post updates on their residents, and you can support their care through donations since they don't take "tourist money" for tickets.
- Adjust your expectations. The era of "animal acts" on the Strip is basically over. Focus your itinerary on the high-tech immersive stuff like Sphere or the botanical displays at Bellagio, which offer that "wow" factor without the ethical baggage.
The Secret Garden is gone, but the stories of those white tigers will be part of Las Vegas lore forever. It was a weird, beautiful, controversial, and quintessentially Vegas experiment that simply ran its course.
