The facility was founded in 1980 and was originally located near Boulder before relocating to its current, much larger site in Keenesburg.
The elevated walkway is the longest footbridge system of its kind in the world, spanning over 1.5 miles.
Many of the lions and tigers residing here were rescued from 'backyard breeder' situations where they were kept in small, concrete cages.
The sanctuary does not purchase, breed, sell, or trade any animals.
The acreage is divided into large, specialized habitats tailored to the specific geographical and behavioral needs of different species.
The sanctuary operates a dedicated rescue department that travels across the United States to transport animals in specialized trailers.
Some habitats include artificial lakes or ponds to accommodate species like tigers, which frequently enjoy swimming.
The facility serves as a research site for wildlife biologists studying the social structure of captive carnivores in large-acreage settings.
The Wild Animal Sanctuary in Keenesburg, Colorado, is the world's oldest and largest nonprofit sanctuary dedicated exclusively to rescuing and caring for captive large carnivores. The facility spans over 789 acres of open grassland, housing more than 500 animals, including lions, tigers, bears, wolves, and leopards. It utilizes a unique 'Mile Into the Wild' elevated walkway system, allowing visitors to observe animals in large-acreage natural habitats from above without disturbing them. Unlike traditional zoos, the sanctuary functions as a refuge for animals rescued from illegal private ownership, circuses, and neglected roadside attractions. The animals are grouped into social prides or packs whenever possible to encourage natural behaviors. The site features an educational visitor center and dedicated areas for veterinary care and nutrition management. Its primary operational focus is long-term welfare, rehabilitation, and advocacy rather than entertainment-based breeding or public interaction.
The elevated walkway segments that overlook the central lion habitats provide the most direct lines of sight for photography.
Wear comfortable, closed-toe walking shoes as the elevated boardwalk covers significant distance.
Bring binoculars for better visibility, as animals may roam far from the walkway into their large habitats.
Pack sun protection, such as a hat and sunscreen, as the boardwalk is entirely exposed to the elements with minimal shade.
Do not visit during the peak heat of summer afternoons, as animals often seek shelter and shade, making them difficult to spot.
Open daily year-round, weather permitting; may close during extreme high winds or blizzard conditions common in Colorado.
Maintain a quiet volume to avoid stressing the animals; do not attempt to feed, whistle, or call out to residents.
