Cal Fire is warning people about the dangers of hiking trails. This comes after two people have died at Three Sisters Falls this month. There have been more than a dozen helicopter rescues this year already and first responders say they expect more. “It’s a dangerous place, it’s a natural place, keep it in mind," avid hiker, Jacob McMahan. “It’s very strenuous if you do it during the day, you’re going to be in the dead sun so that’s going to be the hardest time," he continued. McMahan is an avid hiker, and has hiked this trail several times, but even he says it can be challenging. "The hardest part of the hike is hiking out so you gotta save all your water for that," added McMahan. "On the hike down its all downhill into a valley so on the way back up it’s a little harder," said hiker, Josh Brophy. Cal Fire is now reminding hikers to come prepared.
