As spring arrives in Texas and New Mexico, hikers are being warned to be cautious of rattlesnake encounters at popular outdoor destinations like Palo Duro Canyon, Carlsbad Caverns, and other national parks and natural areas. Rattlesnakes become more active in warmer weather, posing a potential risk to visitors, though experts say the snakes generally avoid confrontation if left alone.

Why it matters

Rattlesnake sightings are common in many parts of the Southwest, but the influx of hikers and outdoor enthusiasts in the spring can increase the chances of accidental encounters. While rattlesnake bites are rarely fatal if treated promptly, they can still cause serious injury, making awareness and caution crucial for visitor safety in these areas.

The details

Certain regions in Texas and New Mexico are known hotspots for rattlesnake activity, including Palo Duro Canyon, Big Bend National Park, Carlsbad Caverns National Park, and the Gila National Forest. As temperatures rise, the venomous snakes emerge from their winter dens and become more visible to hikers and outdoor recreationists. Experts advise that if a rattlesnake is encountered, the best response is to slowly back away and give the snake space, as they generally avoid confrontation unless threatened.

  • As the weather warms up in spring, rattlesnakes become more active and visible to hikers in Texas and New Mexico.
