Alligators aren't exactly what you'd expect to find in the San Luis Valley.

This is a place known for its high-altitude farmland, mountain views, cold winters, and wide-open spaces. Yet just outside Mosca, visitors can encounter alligators, crocodiles, turtles, and other reptiles at an attraction that seems more at home in Florida than southern Colorado.

But Colorado Gators Reptile Park didn't begin as a tourist attraction. Its story started with fish, warm water, and an unexpected solution to a practical problem.

From Fish Farm to Alligator Attraction

The story began in 1977, when Erwin and Lynne Young established a fish farm on approximately 80 acres near Mosca.

The family planned to raise tilapia, a warm-water fish that could be sold for food. There was one important advantage to their location: geothermal water.

Although San Luis Valley winters can be bitterly cold, naturally heated groundwater beneath parts of the Valley provides an unusual opportunity for raising species that ordinarily require much warmer climates.

The Young family used that resource to maintain ponds suitable for tilapia. The operation grew, but eventually the family faced a problem that would change the direction of the business.

What should they do with all the leftover fish?

In 1987, the Youngs came up with an unconventional answer: buy 100 young alligators and let them consume the fish-processing waste.

It was a practical solution, although hardly an ordinary one for a Colorado farm.

The alligators thrived in the warm water, and before long, word spread that there were real alligators living in the San Luis Valley.

People wanted to see them.

By 1990, the family had opened the property to visitors, and Colorado Gators was on its way to becoming one of the state's most unusual roadside attractions.

How Alligators Survive Colorado Winters

One of the first questions visitors ask is how animals associated with warm southern swamps can survive at an elevation of approximately 7,500 feet.

The answer lies beneath the ground.

Geothermal water supplies the warmth necessary for the alligators and other cold-blooded animals. Because reptiles depend on external heat sources to regulate their body temperature, access to appropriately heated environments is essential.

Without those conditions, the San Luis Valley's freezing winters would make outdoor survival impossible for tropical and subtropical reptiles.

The geothermal resource that originally made fish farming possible remains central to the operation.

More Than an Alligator Farm

Over the years, Colorado Gators evolved into something much more than a place to see alligators.

The park became a refuge for unwanted and surrendered reptiles, including animals that had outgrown their owners' ability to care for them.

A small alligator or exotic snake might seem manageable when first purchased, but some reptiles grow remarkably large, require specialized diets and housing, and can live for decades.

Colorado Gators provides a home for many animals whose owners could no longer meet those needs.

Today, the park advertises hundreds of rescued reptiles, including alligators, crocodiles, caimans, tortoises, and turtles. Visitors can also learn about the challenges of keeping exotic animals responsibly.

Morris: Remembering Colorado Gators' Hollywood Star

Among the park's most famous residents was Morris, an alligator with an unusual connection to Hollywood.

Morris appeared in several movies, including the 1996 comedy Happy Gilmore, starring Adam Sandler, as well as Interview with the Vampire and Dr. Dolittle 2.

After retiring from show business in 2006, Morris found a permanent home at Colorado Gators, where he became one of the park's best-known attractions.

For nearly two decades, visitors to the San Luis Valley had the opportunity to see an animal that had shared the screen with some of Hollywood's biggest stars.

Sadly, Morris died in May 2025 at an estimated age of at least 80 years.

His passing attracted national attention, including a tribute from Adam Sandler, who remembered his unusual co-star from Happy Gilmore.

But Morris's story did not end there.

In 2026, Morris reportedly returned to Colorado Gators as a preserved taxidermy exhibit, allowing visitors to learn about the remarkable life of the park's most famous resident.

His story remains one of the most unusual connections between the San Luis Valley and Hollywood.

A Devastating Fire and a Determination to Rebuild

Colorado Gators experienced one of its most difficult moments on April 18, 2023.

An early morning fire destroyed a reptile building, killing many rescued snakes, lizards, tortoises, parrots, and other animals housed inside.

No people were injured, and the alligators and crocodiles housed outside the affected building survived.

The tragedy was a major setback for the family and the rescue operation.

But the park reopened to visitors later that month, and rebuilding efforts followed. By October 2023, construction crews were installing a new concrete floor with geothermal heating pipes for the replacement reptile facility.

The recovery demonstrated how much the operation had grown beyond its original purpose as a fish farm.

An Unexpected San Luis Valley Landmark

Part of Colorado Gators' appeal is the contrast between its animals and its surroundings.

Visitors traveling through the northern San Luis Valley see farmland, open rangeland, distant mountains, and a landscape shaped by agriculture and geothermal activity.

Then, seemingly out of nowhere, they encounter a reptile park filled with animals normally associated with much warmer parts of the world.

For travelers visiting Great Sand Dunes National Park and Preserve, Colorado Gators offers another distinctive stop in the same general area.

For Valley residents, it is also a reminder that some of the region's most interesting businesses developed from people finding creative ways to make use of local resources.

What began as a way to dispose of leftover fish became a family-operated attraction, a reptile refuge, and an educational destination.

And it all happened because a Colorado fish farmer decided that alligators might be the answer to a problem.
