The St. Louis Post-Dispatch reports that the man had been found by a passing bicyclist off the Katy Trail in the Weldon Spring Conservation Area on Tuesday.
Kyle Gaines is a spokesman with the St. Charles County Ambulance District. He says the man was taken to a hospital in serious condition, but his injuries aren’t believed to be life-threatening. Gaines says further details about the man won’t be released due to privacy laws.
Gaines advises state park visitors to take plenty of water and a fully charged phone when going to the trail in hot temperatures.
The park is a wooded area spanning nearly 8,400 acres.
