A hiker who left the trail on Mount Rubidoux and found herself stuck on the hillside was rescued Tuesday, Aug. 29, the Riverside Fire Department said.

The hiker, in her 40s, went out for a walk about 11 a.m. and entered a ravine below the castle, Battalion Chief Tony Perna said. About noon, she called 911 and said she could not complete the trip down or climb back up. Firefighters summoned a helicopter to help locate her.

“Where she was sitting down, you couldn’t see her from the road,” Perna said.

Firefighters lowered themselves to the hiker, put her in a basket and brought her up to the trail. She was anxious and dehydrated, Perna said. She did not have any water with her, Perna said, on a day in which the high reported temperature in Riverside was 108 degrees. The hiker was hospitalized.

Perna advises hikers never to go it alone, to bring plenty of water and a telephone and to go out before or after the hottest times of the day.
