Reptile Gardens: The World's Largest Reptile Collection

The story of Reptile Gardens begins, as the founder liked to tell it, with a rattlesnake under a hat. Earl Brockelsby was a young man working in the Black Hills tourist trade in the early 1930s, and he discovered that travelers passing through were fascinated by the rattlesnakes that the region had in abundance. He took to keeping a live one coiled under his hat and revealing it for tips and astonishment. From that bit of roadside showmanship grew the idea that there might be a living in snakes, if a person presented them well enough.

Brockelsby opened his attraction along the highway south of Rapid City in the 1930s, in the corridor running toward Mount Rushmore and the interior of the Hills that was just then filling with cars and curious tourists. It was a modest thing at first, a place to see snakes and other reptiles up close, pitched at the families driving the new scenic roads. But it caught on, and over the following decades it grew steadily, adding species, buildings, and shows until it had become one of the largest reptile collections anywhere and a fixture of the Black Hills tourist circuit.

A serious collection behind the spectacle

What separated Reptile Gardens from the run of roadside curiosities was the breadth and seriousness of what it gathered. Behind the carnival appeal of snake handling lay a genuine and growing collection of reptiles from around the world, including crocodilians, giant tortoises, lizards, and venomous snakes that few visitors would ever otherwise see. The attraction came to bill itself, with some justification, as holding the largest reptile collection of its kind, and it backed the claim with the variety of animals on display.

The shows became part of the draw. Handlers worked with rattlesnakes and other venomous species in front of crowds, demonstrating the animals’ behavior and dispelling some of the fear that surrounded them, and the performances combined real expertise with a frank sense of theater. Alongside the reptiles, the grounds developed extensive botanical displays, so that the gardens lived up to the second half of their name as well as the first. The combination of dangerous animals, careful horticulture, and family-friendly showmanship proved durable in a way that many roadside attractions did not.

Part of the Black Hills draw

Reptile Gardens grew up in the same decades that turned the Black Hills into a national tourist destination, the era of scenic highways, Mount Rushmore, and the whole apparatus of signs and stops that lured motorists off the main roads. It belongs to a particular family of attractions that the region produced in number, places like the wildlife park at Bear Country USA and the gravity illusion at the Cosmos Mystery Area, each offering the passing traveler a reason to pull over. Many such places came and went. Reptile Gardens endured, passing through the founding family’s hands across generations and remaining in operation long after Brockelsby’s hat trick had become company legend.

Its endurance says something about how the Black Hills tourist economy actually worked. The grand sights, the carved mountain and the deep caves and the state parks, drew people to the region, but the smaller roadside attractions captured them once they arrived, turning a single destination into a week of stops. Reptile Gardens learned that lesson early and worked it for decades, building a reputation that reached well beyond South Dakota. From a rattlesnake under a hat to a sprawling collection visited by travelers from across the country, it became one of the more unlikely success stories of the Black Hills road, and one of the most familiar names on the long list of things to see south of Rapid City.
