"It's so hard to believe that one of your kids is lost and you don’t know how they are, if they have water, if shes dehydrated. You want the best for your kids but I’m so happy right now," said the hiker's mother, Gloria Coronado.
The hiker, identified as Zaira Hernandez, called her friend around 12:30 p.m. to tell her she was lost and disoriented, San Diego police spokeswoman Andra Brown said. Hernandez's cellphone went dead or was turned off, Brown said.
"She was disoriented out here. She was at the top of a hill according to the communication she had with the park ranger," said Brown.
Around 4:15 p.m., Hernandez reached a house in Scripps Ranch and asked a resident to use their home to call police. Police were on their way to the house to pick her up and reunite Hernandez with her mother at the parking lot in Mission Trails.
"Your head goes forward thinking things that you’re not supposed to think, but I’m so happy she’s alive and she’s with us," said Coronado.
A sheriff's helicopter crew and volunteer search teams took part in the efforts to find her.
Hernandez was wearing a black shirt, black pants and did not bring water with her.
