Two teens were injured during a hike at Stone Mountain Park on Tuesday.
Police said they were in a restricted area. It happened on the back side of the mountain in an area called the Bird Sanctuary. News Chopper 2 flew over the area as emergency crews transported the victims around lunchtime.
"It's restricted because it's dangerous and if you don't know what you're doing, if you're not trained in this particular area of the mountain, then you need to stay away from it. This goes to show you why it's restricted," Stone Mountain Park police spokesman John Bankhead said.
He said a man was on a hike with his 12-year-old son and two teens when they wandered into the area. There are signs restricting the public, and it's fenced off at the top, but Bankhead said there are ways around that.
"They started up the mountain, didn't notice any signs about the restricted area and came off the back side of the mountain, where they're not supposed to be," Bankhead said.
He said the teens, ages 17 and 18, slid down a pipe and tumbled down the mountain.
"One of the kids saw this pipe and decided to go down it for some reason, started to slide but couldn't stop. The second kid, the older kid, went after him, and that's when the problems happened with those two," Bankhead said.
He said they fell several hundred feet. The adult with the group told the 12-year-old to stay put, and he called 911, Bankhead said.
The teens were taken to the hospital. Bankhead said their injuries are serious, and that the other two were not injured.
