It’s weird walking past the Mirage these days. If you’ve been to Las Vegas lately, you’ve probably noticed the vibe is shifting. Hard. The iconic volcano is on borrowed time, and the Hard Rock "Guitar Hotel" transition is looming over the Strip like a giant neon shadow. But for many long-time Vegas fans, the biggest sting wasn't the loss of a fake volcano. It was the permanent closure of Siegfried and Roy’s Secret Garden and Dolphin Habitat.
For decades, this place was a weirdly peaceful anomaly. You’d step off the blistering, booze-soaked asphalt of Las Vegas Boulevard and suddenly you were surrounded by tropical greenery and the smell of salt water. It felt permanent. It felt like the soul of the Mirage. Then, in late 2022, it just… stopped.
Most people think it closed because the Mirage was sold. That's part of it, sure. But the reality is a lot more complicated, involving shifting public opinions on animal captivity and a string of unfortunate events that made the "Secret Garden" a lot less magical toward the end.
The Mirage Transition and the End of an Era
Hard Rock International bought the Mirage operations from MGM Resorts for over a billion dollars. When a new owner takes over, they usually want to scrub the old identity. Hard Rock wants rock stars and guitar-shaped towers, not white tigers and bottlenose dolphins.
But the closure of Siegfried and Roy’s Secret Garden and Dolphin Habitat actually happened ahead of schedule. Originally, people thought the animals might stay until the full renovation started in 2024. Fate had other plans. In the months leading up to the closure, the habitat faced significant scrutiny. Three dolphins died in a single year—Bella, Maverick, and K2. That’s a staggering loss for any zoological facility.
The public outcry was loud. Activist groups like Free the Mojave Dolphins had been banging on the gates for years, but the sudden spike in mortality rates made the situation untenable for a brand trying to undergo a massive corporate rebranding. It wasn't just about "making room" for a new hotel. It was about a changing world where keeping apex predators in the middle of a desert was becoming a PR nightmare.

Where Did the Animals Actually Go?
This is the question everyone asks. You can't just put a white tiger on Craigslist.
The transition was a massive logistical headache. For the dolphins, the destination was the Caribbean. Specifically, Coral World Ocean Park in St. Thomas, US Virgin Islands. The move happened in early 2023. It wasn't just a simple flight; we're talking about specialized tanks, veterinary teams, and a massive amount of coordination to move highly social mammals across the ocean. Honestly, it was probably the best-case scenario for them. They moved from a chlorinated tank in the desert to a sea-pen environment where they can actually feel the natural tides.
The big cats? That’s a different story. Siegfried and Roy’s legacy was built on those white tigers and lions. After the facility shuttered, the cats were relocated to San Diego. Specifically, they went to WildWonders in Bonsall and the San Diego Zoo Safari Park.
- WildWonders is a private, accredited facility that focuses on conservation and education.
- San Diego Zoo Safari Park is world-renowned for its massive enclosures.
It’s a bit bittersweet. On one hand, the "Secret Garden" is gone. On the other, these animals are now in facilities with far more space and specialized long-term care plans that aren't tied to a casino's bottom line.
Why the "Secret Garden" Still Matters to Vegas History
Siegfried and Roy weren't just magicians. They were the reason the Mirage existed. Steve Wynn basically built the hotel around their show. Before they showed up, Vegas was mostly about cheap shrimp cocktails and smoky gambling dens. They brought the "spectacle."

The Siegfried and Roy’s Secret Garden and Dolphin Habitat was their way of staying connected to the property even after the 2003 incident where Montecore—the tiger—bit Roy on stage. Even after the show ended, the habitat remained a pilgrimage site. You’d see fans leaving flowers near the statues. It was a living monument to a specific era of Las Vegas that is rapidly being demolished.
Honestly, the "Secret Garden" was one of the few places on the Strip where you could actually breathe. It was quiet. The lush foliage muffled the sound of the slot machines. Losing that greenery for more casino floor space or a giant guitar-shaped building feels like losing a piece of the city's lungs.
The Controversy You Might Have Missed
While the tourists loved the dolphins, the zoological community was often divided. The "Dolphin Habitat" was essentially a series of interconnected pools. No natural shade. No sand. Just blue concrete and treated water. In the 110-degree Vegas summers, keeping those pools cool enough for the animals was an engineering feat, but many argued it was fundamentally unethical.
Critics often pointed out that the dolphins showed signs of repetitive behaviors—what biologists call "zoochosis." They’d swim in the same circles for hours. While the trainers clearly loved the animals and provided top-tier medical care, the environment itself was a relic of 1980s design.
When the facility closed, it marked a turning point. You won't see another casino open a dolphin exhibit. Those days are over. The trend now is toward "digital" entertainment—think the Sphere—rather than live animal attractions.

What to Do Instead: Finding the "Old Vegas" Vibe
If you’re heading to Vegas and you’re bummed out that you can't see the Siegfried and Roy’s Secret Garden and Dolphin Habitat, you’ve got to pivot. The Strip is becoming a corporate monoculture, but there are still spots that capture that weird, curated nature vibe.
- The Bellagio Conservatory & Botanical Gardens. It’s free. It’s massive. They change the theme five times a year. It’s the closest thing you’ll get to the lushness of the Secret Garden.
- The Flamingo Wildlife Habitat. It’s still there! You can see Chilean flamingos, pelicans, and turtles. It’s right in the middle of the Flamingo hotel grounds. It’s smaller, but it’s a great place to escape the noise.
- The Springs Preserve. If you actually want to learn about the Mojave desert, go here. It’s off-strip, but it’s 180 acres of botanical gardens, trails, and exhibits. It’s where the locals go when they need a break from the neon.
The Technical Side of Moving a Lion
Moving a 400-pound lion isn't like moving a house cat. When the Siegfried and Roy’s Secret Garden and Dolphin Habitat animals were relocated, it involved specialized "transport crates" that are essentially armored rooms on wheels.
The cats have to be crate-trained for weeks before the move. You don't just tranquilize them and toss them in a truck; that's dangerous for their respiratory systems. Trainers use "positive reinforcement" to get the lions to walk into the crates willingly. They use treats (lots of raw meat) to make the crate feel like a safe space.
By the time the actual moving day came for the Mirage lions, they were basically ready to take a nap in their travel boxes. This level of care is why the relocation took months to complete. It wasn't a "clear out the building" situation; it was a "wait until the animals are emotionally ready" situation.
Actionable Insights for Your Next Vegas Trip
If you’re planning a trip and want to see the remains of the Mirage before it’s gone forever, time is running out.
- Visit the Statues: The bronze statues of Siegfried and Roy are still a major photo op near the front entrance. They likely won't survive the Hard Rock renovation in their current spot, so get your pictures now.
- Check the Construction Schedule: As of now, the transition is in full swing. Parts of the old habitat area are already walled off. Don't expect to get close to the old dolphin pools.
- Support Accredited Sanctuaries: If you miss the animals, consider donating to or visiting the San Diego Zoo Wildlife Alliance. They are the ones actually doing the work to ensure the Mirage’s former residents live out their lives in peace.
- Don't Believe the Rumors: You might hear people say the animals were "put down" or sold to circuses. That’s nonsense. The relocation to St. Thomas and San Diego is well-documented and overseen by federal agencies under the Marine Mammal Protection Act and the USDA.
The era of the Siegfried and Roy’s Secret Garden and Dolphin Habitat is officially in the history books. It was a product of a different time—a time of big hair, white tigers, and "more is more" architecture. While it’s sad to see a landmark go, the fact that the animals ended up in high-quality sanctuaries is a win. Las Vegas is a city that constantly reinvents itself, usually by tearing down its past. This is just the latest chapter in that never-ending cycle of demolition and rebirth.
