If you’re typing "wild animal sanctuary Denver" into your phone while sitting in a LoDo coffee shop, you’re probably looking for lions. Or tigers. Or maybe a bear that was rescued from a tiny cage in someone's backyard.
Here is the thing. There isn't actually a massive, sprawling carnivore sanctuary right in the middle of downtown Denver. That would be chaotic. Honestly, the real deal—the place everyone is actually talking about—is located about 30 miles northeast of the city in Keenesburg. It’s called The Wild Animal Sanctuary, and it is unlike any zoo you’ve ever visited.
It's huge.
Most people expect a couple of acres and some chain-link fences. Instead, you get over 1,200 acres of open prairie where rescued animals finally get to be, well, animals. It is the oldest and largest nonprofit carnivore sanctuary in the world. Since 1980, Pat Craig and his team have been pulling animals out of horrific "roadside zoos," circus trailers, and illegal private basements.
Why the "Mile into The Wild" walkway is a big deal
When you show up, you don't walk along the ground. That’s the first thing that catches people off guard.
You walk on a massive, elevated bridge. It’s called the Mile into The Wild walkway. It stretches for about 1.5 miles over the habitats. Why? Because in the animal world, "territory" is everything. If you walk up to a tiger's fence at eye level, you are a threat. Or a snack. Or at the very least, an annoyance. But when humans are 20 feet up in the air, the lions and bears basically stop caring about us. They don't feel like their space is being invaded.
It’s a weird feeling. You’re looking down at a pride of African lions lounging in the Colorado sun, and they don't even look up. They’re just living.
This layout is essential for the rehabilitation of animals coming from the "Tiger King" style environments. Many of the residents at the Wild Animal Sanctuary Denver travelers visit were formerly kept in tiny cages where they could barely turn around. Moving to a 20-acre pasture is a massive psychological shock. The elevated walkway allows them to acclimate without the constant stress of thousands of faces pressed against their enclosures.

The staggering cost of keeping a tiger fed
Let’s talk money for a second because people rarely realize how expensive it is to run a place like this.
We aren't talking about cat food from the grocery store. We are talking about tens of thousands of pounds of raw meat every single week. The sanctuary spends a fortune on high-quality nutrition and specialized veterinary care.
- They have a state-of-the-art hospital on-site.
- Most rescued animals arrive with "Metabolic Bone Disease" from poor diets.
- Dental surgeries for tigers are surprisingly common (and expensive).
They don't get government funding. It’s all donations. When you pay your entrance fee—which, heads up, is more of a "donation" structure than a cheap movie ticket—you are literally buying lunch for a grizzly bear. Or helping pay for the massive semi-trucks they use to rescue animals from across the country.
Bolthouse Ranch and the expansion of the mission
While the Keenesburg location is the one most folks visit, there is a second, even larger site that most people don't know about. It's called the Refuge.
Located in southern Colorado near Springfield, the Refuge consists of nearly 10,000 acres of forested canyons. It isn't open to the public in the same way the main sanctuary is. It's designed for the animals that need even more seclusion—the ones who really just want to disappear into the woods and never see a human again.
This is the "end game" for many of these rescues. After years of being poked and prodded in cages, they get to retire in a canyon that looks exactly like their natural habitat. It’s arguably the most ambitious animal welfare project in North America right now.
Common misconceptions about the sanctuary
People often get confused and think this is just another zoo. It isn't.

In a zoo, the animals are usually on display for your benefit. They are positioned so you can see them clearly. At the Wild Animal Sanctuary, if a bear wants to nap in a hole for six hours where you can't see him, he does.
There are no shows. No "animal encounters." No petting the cubs.
Honestly, if you see a place offering "tiger cub photos," you should run the other direction. Those places are the primary reason sanctuaries like this need to exist. Once those cubs grow up and become dangerous, they are often dumped or killed. The Wild Animal Sanctuary is the place that picks up the pieces of that broken industry.
The 2026 outlook for wildlife rescue
As of early 2026, the sanctuary is seeing a shift in where rescues are coming from. While "private owners" are still a problem, we are seeing more rescues from international situations where zoos in war-torn regions or failing economies can no longer care for their animals.
Logistically, moving a lion from a conflict zone to a quiet field in Colorado is a nightmare. It involves international permits, custom-built crates, and chartered flights. But they do it.
Planning your trip: What to actually bring
If you’re going to make the drive from Denver, don't be a rookie.
- Check the wind. The sanctuary is on the high plains. If it's windy in Denver, it’s a hurricane in Keenesburg.
- Bring binoculars. Since the habitats are so big, the animals might be a few hundred yards away. You’ll want the extra zoom.
- Go late. Most of these animals are crepuscular (active at dawn and dusk). If you go at noon in the middle of July, you’re going to see a lot of sleeping rocks that happen to have fur. If you go closer to sunset, the lions start "woofing" and the wolves start howling. It’s haunting and beautiful.
Wear comfortable shoes. You’re walking over a mile on that bridge. It’s a workout.

Ethical considerations of "Wild Animal Sanctuary Denver" searches
There is a growing debate about "wildlife tourism." Some critics argue that any form of keeping wild animals in captivity is wrong.
However, the sanctuary’s stance is pragmatic: these animals can never go back to the wild. A tiger born in a basement in Ohio doesn't know how to hunt in the jungles of India. It has no "home" to return to. Therefore, the most ethical option is to give them the largest, most natural space possible where they can live out their lives with dignity.
They also focus heavily on education. They want you to leave feeling a bit angry that these animals needed saving in the first place.
How to get involved beyond just visiting
Most visitors feel a pretty strong pull to do more after seeing the scale of the operation. You can actually "adopt" an animal, which is basically a recurring donation that covers their specific food and medical needs. You get a photo and their backstory. It makes the connection a lot more personal.
They also have a massive volunteer program, though be warned: you won't be cuddling lions. You’ll be cleaning enclosures, preparing food, and doing the heavy lifting that keeps the facility running.
Actionable steps for your visit
If you are ready to head out, follow these steps to make sure the trip is worth it:
- Verify the hours: They sometimes close for extreme weather or special rescue arrivals. Always check the official Wild Animal Sanctuary website before you leave Denver.
- Dress in layers: Even if it's 70 degrees in Denver, the plains get chilly fast once the sun starts to dip.
- Pack water and snacks: There is a small cafe (the Lion's Den), but having your own supplies is always smarter when you're out on the walkway.
- Silence your phone: Part of the magic is the silence of the prairie. Don't be the person blasting a TikTok video while everyone else is listening to a tiger chuff.
- Budget at least 3-4 hours: Don't try to squeeze this into a 60-minute window. You need time to sit, observe, and wait for the animals to move.
Seeing these creatures in a space where they aren't pacing nervously against a glass wall changes your perspective on wildlife forever. It's a somber experience, but a hopeful one. You realize that while humans caused the problem, humans are also the ones putting in the work to fix it.
Drive safe on I-76. Watch for the signs for Keenesburg. It’s a straight shot, and once you see the elevated walkway rising over the horizon, you’ll know you’re in the right place.
Next Steps for Your Visit:
Before heading out, download a bird or wildlife identification app. While the lions are the stars, the sanctuary is also a haven for native Colorado hawks, eagles, and foxes that roam the property freely. Checking the "Animal Stories" section on the sanctuary’s website before you arrive will also help you identify specific residents by name, like the bears rescued from the "concrete pits" or the lions from South American circuses, making the experience significantly more impactful.
