When we were there we didn’t see any and that was July 4th 2019 just rain.

We stayed out of the grassy areas for this reason we even kept our dogs out of it there was one time though that there was what we think was a prairie rattlesnake in the dirt road and whenever kids was able to see it in time but it quickly went back into the grass

I didn’t see any when we stayed 3 nights ago

We didn't see any and it's not likely they would be there with all the activity however, there are snakes (with lots of warnings) on hiking trails in the Badlands. Didn't see any though.

Supposedly rattlesnakes in the area. I have never ONCE seen one or heard one. We come here every year.

was there last July，didn't see any.

I stayed for 5 nights and never saw any snakes. Several bighorn sheep though!

Been there two times, not more than three days each time. Didn’t see any snakes.

If there are we didn’t see any.

We never saw any snakes while we were there but I am not saying that it doesn’t have snakes. We enjoyed camping there.

There are snakes everywhere. But I never saw one while we were there.
