The 67-year-old heir to the throne was unhurt in the Balmoral estate incident, which took place in recent days, 'Daily Mirror' reported.
While his Clarence House office has declined to comment on the incident, Charles is believed to have been driving an Audi A4 Allroad Estate when the accident happened.
He wasn't hurt but the vehicle was left so badly damaged that a specialist mechanic was despatched to the royal estate in the Highlands to repair it, the newspaper claims.
Balmoral, the British monarch's Scottish home where she usually spends the English summer, is playing host to a huge royal gathering this week.
