Teens rescued from SA cliff

Three boys have been winched to safety after being stuck on a cliff on the South Australian coast.

Emergency services were called to cliffs near the camping ground at Second Valley just before 6pm on Tuesday to winch three 15-year-old boys out of an inaccessible area.

The boys were treated for minor scratches and grazes and one was taken to hospital as a precaution.

A fourth boy was able to get himself to safety.
