At about 11:30 a.m., Oakland fire crews responded to a report that a boy who was camping in the area fell and hit his head on an asphalt surface, according to Battalion Chief James Bowron.
The boy, who was camping with a group at the Anthony Chabot Family Campground off of Redwood Road, appeared to have suffered significant head trauma and was stabilized by paramedics before being airlifted to UCSF Benioff Oakland Children's Hospital, Bowron said.

The campground is in an unincorporated part of Alameda County east of Oakland and is usually served by county fire crews. However, a landslide that closed part of Redwood Road has prevented access to the area from the south, where the nearest county fire station is located, Bowron said.
Emergency response personnel from the East Bay Regional Park District also responded to the scene.
