SAN FRANCISCO (CBS SF) — A father and his young child were safely rescued from a cliff at Fort Funston on Saturday morning, fire officials said.

The pair were out for a walk about 11:30 a.m. and tried to hike down the cliff to reach the water below, but became stuck about 70 feet down, said San Francisco Fire Lt. Jonathan Baxter on social media.
