Want to check out the biggest snakes in Dallas? We’re not talking about a trip to City Hall, but rather a visit to one of Oak Cliff’s own gems, the Dallas Zoo.

Billed as one of the premier reptile and amphibian collections in the United States, the reptile house at the Dallas Zoo is a great place to escape the heat and check out some truly amazing and sometimes bizarre sights.

Whether you are a kid, or just a kid-at-heart, the reptile house always delights and fascinates. Finding yourself eye-to-eye with a venomous pit viper, separated by a seemingly invisible pane of glass, can send a shiver up even the most macho spine. There is something about snakes and lizards that give them the ability to simultaneously repulse and attract your attention.
