World’s Largest Snake Gathering: Discover Manitoba’s Narcisse Snake Dens
C
an you imagine that just 110 kilometers from Winnipeg, the lively capital of Manitoba with a population of just over 800,000, lies one of the world’s most incredible wildlife spectacles? Each spring, tens of thousands of red-sided garter snakes emerge from their limestone dens, shaking off the long grip of the harsh Canadian winter. These snakes slither in overwhelming numbers, driven by a primal instinct to mate before disappearing into their summer habitats. The sight of them coiling and writhing in the sun is nothing short of breathtaking, drawing in both curious tourists and dedicated wildlife researchers from around the globe. Witnessing so many snakes in one place is truly mesmerizing and an unforgettable experience for anyone brave and lucky enough to see it.

Spring is just part of their incredible journey. As summer fades and the crisp autumn air rolls in, the snakes find their way back to the dens for another reason: to survive the long, brutal winter. By early fall, the dens once again transform into safe havens as the snakes gather in large numbers, seeking shelter in the underground caves. These natural refuges protect them from the deadly cold and lurking predators, allowing them to hibernate and endure the winter months in dormancy. It’s a cycle of survival and renewal that has repeated itself for centuries, a natural wonder that highlights nature’s extraordinary ability to adapt and thrive, even in the most unforgiving environments.
The Narcisse Snake Dens are nestled in Manitoba’s Interlake region, renowned for its limestone sinkholes that create a haven for garter snakes during the harsh Canadian winter. Accessible via a network of scenic hiking trails, featuring viewing platforms carefully designed to allow visitors to observe the snakes without disturbing them, the area is more than just a single location. The surrounding region is teeming with ideal dens, scattered across the landscape, with some nestled on private lands, creating a rich tapestry of habitats for these fascinating creatures.

The red-sided garter snake (Thamnophis sirtalis parietalis) takes the spotlight in this remarkable spectacle. These non-venomous snakes are easily recognizable by their distinct red stripes running along their sides. What truly sets apart the Narcisse snake population is their sheer numbers congregating in one place. During the spring mating season, thousands of males gather to court the fewer females, forming dense mating balls where dozens of snakes intertwine a sight that captivates wildlife enthusiasts.
The red-sided garter snake’s range spans from northwestern Ontario to eastern British Columbia, with isolated populations in the southern Northwest Territories and northern Alberta. It extends south through the central United States to Texas. This subspecies thrives in a variety of habitats during its active season, including forests, shrublands, wetlands, fields, and rocky areas. Come winter, they hibernate below the frost line in burrows, rock crevices, and even anthropogenic structures like old foundations and cisterns. These deep, frost-free hibernation sites are critical, allowing them to survive farther north than any other land-dwelling reptile in Canada.

Red-sided garter snakes often seek shelter and regulate their temperature under cover objects such as rocks and logs. Breeding typically occurs in spring soon after emerging from hibernation, with fall mating frenzies occurring in some areas near hibernation sites. Females give birth to 10-30 live young in midsummer, each measuring 19-23 cm long at birth and reaching maturity in two to three years. After breeding, they may travel several kilometers from hibernation sites to foraging grounds but return to the same den come fall.

Due to the rarity of suitable hibernation sites, hundreds or even thousands of snakes can gather in a single hibernaculum. Red-sided garter snakes are diurnal foragers, consuming a diverse diet that includes frogs, toads, salamanders, earthworms, insects, small fish, small mammals, and occasionally birds and eggs. With a lifespan exceeding twenty years, these snakes exemplify resilience and adaptation in their quest for survival across diverse North American landscapes.

The Narcisse Snake Dens are crucial to our local ecosystem. Red-sided garter snakes play a vital role in keeping populations of small mammals, insects, and amphibians in check, which helps maintain a balanced food web. Their hibernation sites serve as vital components of a larger ecosystem, providing shelter for various species including birds and small mammals. Protecting these snake dens is essential for the snakes and preserving the rich biodiversity of Manitoba’s unique prairie landscape.
The Manitoba government has established multiple viewing platforms and designated trails surrounding the snake dens to mitigate human impact. It’s vital to adhere to guidelines: stay on marked paths and refrain from disturbing the snakes. Ethical wildlife viewing is essential for the ongoing preservation of these remarkable creatures. The Narcisse Snake Dens showcase nature’s beauty, and by respecting these animals and their habitat, we ensure that future generations can cherish this spectacle.
