An Indiana man plunged about 50 feet into a dormant volcano on the Caribbean Island of St. Kitts during his honeymoon — and lived to tell the tale, according to a new report.

Clay Chastain and his wife, Acaimie, flew to the island the day after their wedding in the city of Crawfordsville last month, The Indianapolis Star reported.

On July 18, four days after their arrival, the newlyweds hiked two miles up Mount Liamuiga — and Clay said that he wanted to climb into it for a better view of the lush greenery inside, according to the report.

Amelie stayed behind, fearful of the treacherous climb — and before long, Clay was in danger.

“One second I’m climbing, the next second the world is spinning, and I can hear her calling down to me,” Clay told the outlet.

He believes a rope that he was hanging onto during his descent had snapped, but he can’t say for sure. The next thing he knew, his wife was calling out to him, asking if he was OK, and there was a pile of bloody vomit next to him.

He didn’t respond at first, so Acaimie made her way down herself.

“I was freaking out about what I was going to find at the bottom,” Acaimie told the paper.

When she finally found her husband, she assured him that they’d get out safely.

“We’re going to have to be strong,” Acaimie told the paper she said at the time. “We’re going to have to climb out of here.”

Somehow, Clay had enough energy to climb out and walk two miles down to the volcano’s base — but not without stumbling and vomiting. He leaned on his wife for support.

“It was a miracle that he was able to support himself for as long as he did with the injuries he had,” Acaimie told the outlet.

About halfway down, Acaimie had cell phone service and called 911. Paramedics rushed Clay to a local hospital — where he was treated for a severe concussion, cracked vertebrae, a skull fracture and loss of hearing in his right ear, according to the report.

Air had also gotten into his brain tissue, preventing the couple from taking a commercial flight home. So the pair instead arranged to take a medical flight to Fort Lauderdale, Florida, Wednesday.

“It was just a miracle that he wasn’t injured worse than he was,” Acaimie told the paper. “It was incredible to me that he didn’t have any broken bones.”
