When you think of Colorado, no doubt images of snow-capped mountains come to mind.

However, the state consists of plenty of prairies, where this western state’s most dangerous snakes easily hide, ready to attack their next victim.

So… Are There Snakes in Colorado?

Colorado has close to 30 species of snakes.

Thankfully, only three kinds are venomous to humans, all in the rattlesnake family.

Snake Species in Colorado

The venomous Colorado snakes include three types of rattlesnakes:

• Prairie rattlesnake
• Midget faded rattlesnake
• Western Massasauga rattlesnake

Prairie Rattlesnake

The prairie rattlesnake inhabits most of Colorado and is part of the pit viper family.

They have a potent venom but rarely kill humans since the snake’s size is usually too small to deliver a lethal dose.

Midget Faded Rattlesnake

This rattlesnake breed is considered small, hence the name.

They grow to an adult size of 20 to 30 inches.

Western Massasauga Rattlesnake

Their camouflage coloring hides them in grass where they are difficult to spot.

The Massasauga snake venom contains an enzyme that disrupts blood flow, stopping clotting and destroying tissues in its victims.

Other Colorado snakes include the following:

• Black neck garter snake
• Texas blind snake
• Bull snake
• Western milksnake
• Coachwhip
• Common garter snake
• Speckled kingsnake
• Glossy snake
• Great basin gopher snake
• Great plains rat snake
• Ground snake
• Lined snake
• Longnose snake
• Texas night snake
• Northern water snake
• Plains blackhead snake
• Plains garter snake
• Ringneck snake
• Smooth green snake
• Southwestern blackhead snake
• Striped whipsnake
• Western hognose
• Western terrestrial garter snake
• Yellow-bellied racer

The black pattern on both sides of its neck contributed to its name.

The blackneck garter snake lives in grasslands near water and is the rarest species in Colorado.
