Several people were injured -- including one critically -- when lightning struck near a group of hikers in Colorado on Sunday, according to officials.

The Douglas County Search and Rescue said on Facebook the incident happened around 3 p.m. on the Devil's Head trail in Douglas County, located about 50 miles south of Denver. A total of 8 hikers reported injuries, according to the agency.

“It was easily the scariest thing that will probably ever happen in my life,” Sydney Copeland told FOX31.

Copeland said she was seeking shelter under a rock face wall with her boyfriend and several hikers when the lightning struck. The group was climbing near the Chicken Head Rock area when the bad weather approached suddenly.

“I think from when it first started precipitating to when we all took shelter and got struck -- it was like 10 minutes," she told FOX31. "The girl behind me, I think she got struck and it traveled through my boyfriend to me. She fell forward and was paralyzed pretty instantly.”

After the strike, one of the hikers had to run about a mile and a half in order to get phone service to call 911. Several agencies then responded to the scene and found the hikers all "conscious and breathing."

Seven of the hikers were able to climb out on their own, while an eighth climber was evacuated "via a litter carry" with lightning strike injuries and transported to the hospital, according to the rescue agency. Officials told FOX31 a woman was transported to the hospital and was listed in critical condition.
