Crews brought the man to a nearby hospital for treatment. Officials at the scene said he had been in the remote area of Cleveland National Forest for at least a few of days after his car ran out of gas about 10 miles from where he was found.
The man has not been identified. His medical condition is unknown.
Authorities say the U.S. Forestry Service was able to quickly extinguish the fire before it spread.
The fire started as several large wildfires scorched tens of thousands of acres in both Ventura and Los Angeles Counties.
A long period of Santa Ana winds are expected stretch through the end of the week.
San Diegans may recall a similar act ignited a deadly wildfire in 2003. The Cedar Fire began after a Sergio Martinez, 35, intentionally set a fire south of Ramona so rescue crews would find him. Martinez had become lost from his friend after a day of hunting.
The blaze scorched 270,000 acres, destroyed or damaged more than 2,200 homes and killed 15 people.
Martinez eventually admitted to setting the fire intentionally and was sentenced to five years probation, serving six months in community confinement.
