PHOENIX -- On the hottest day of the year so far, plenty of people turned to the trails Saturday, but the Phoenix Fire Department warns that hiking in this heat is not for everybody.
"We have a lot of avid hikers here in the Valley, and every one of them are more than capable of being out here during this time and enjoying the mountain and enjoying this type of weather. Where we find ourselves in trouble is when we find the people that are not so avid,” said Phoenix Fire Capt. Jonathan Jacobs.
Saturday afternoon, Phoenix firefighters were called to Camelback Mountain's Echo Trail after two men ran out of water and felt fatigued.
"These are advanced mountains. When you add the heat into these mountains and the outside temp like we're looking at today, they become very advanced," Jacobs said.
One man walked down on his own, but the other had to sit in the shade and drink water before he could walk down.
Brandon Hubley was hiking the trails when the temperature hit triple digits. He's from New Mexico, but he said he always makes sure he's prepared for this desert heat.
"Lots of water -- cold water from the freezer," he said.
Phoenix Fire said hydration is key.
"I just try to hydrate all week,” hiker Terri Armijo said.
The fire department said it’s also important for hikers to be realistic about their physical fitness.
“Be realistic about the goals that you are trying to attain,” Jacobs said.
