How to avoid running into a rattlesnake

Also, stay on designated trails. It is important to keep your hands and feet in an area where you can see them.
Rattlesnakes like to hide under rocks and tall grassy areas.
"If you don't put your hands and feet in the wrong place and if you don't provoke rattlesnakes you are totally safe around them," said Dixon.
"When you see one on the trail you should just appreciate it, watch it, don't be afraid of it and be aware that you are here. And when you are here you are actually in their home."
If the snake does not crawl away, turn around and try to enjoy nature another day.
Look around before taking a rest. Rattlesnakes like to hide in shady and cool areas too.
