Hiking trails on Piestewa, Camelback will close during extreme heat

Experience AZ | 22 Jul |

Several of the most popular hiking trails in metro Phoenix, including both trails on Camelback Mountain and those around Piestewa Peak, will be closed temporarily when temperatures rise to unsafe levels, the city Parks and Recreation Board decided Tuesday.

The board approved a pilot program to restrict access to hiking trails whenever an excessive heat watch is issued by the National Weather Service. Phoenix has more than 41,000 acres of desert parks and mountain preserve land, and in 2020, more than 6.2 million hikers visited the trail system, according to a report from park officials.

“To help with that recommendation, extended summer hours are in effect annually from June through September at North Mountain Park and Piestewa Peak Trailhead in the Phoenix Mountains Preserve, and Pima Canyon Trailhead in South Mountain Park/Preserve,” the board said in a news release Tuesday.

The vote came after a request from the United Phoenix Firefighters Association to restrict access to Camelback Mountain and Piestewa Peak because of the number of rescue calls firefighters respond to on those trails. In 2020, there were 284 mountain rescues across the city, including 89 on Camelback and 40 on Piestewa. The 284 rescues were an increase from 255 in 201 and 250 in 2018, according to fire officials.

“We have had several instances of multiple mountain rescues during extreme temperatures, particularly at Piestewa Peak and Camelback Mountain,” said P.J. Dean, secretary-communications director for the union. “One of them was so extreme that we did three (rescues) in one day on the two separate mountains, which resulted in us sending 12 firefighters home mid-shift due to heat-related illnesses.”

Strenuous physical activities in such weather can cause heat stroke, heart attack and other serious health problems for hikers, and rescuers face the added burden of being required to wear 40 pounds of emergency medical equipment to perform rescues, officials said.

“We just want to limit those two parks (Camelback and Piestewa Peak) just because they have a very unique set of circumstances to them where they are a lot more dangerous and a lot more complicated to perform rescues on,” Dean said.

The closures will run from Friday to the end of September, and will be reevaluated by the board in October. Officials also noted that the trails will have “an extra two hours of availability and promote hiking after 7 p.m., parking lot entrances are open until 9 p.m. at those locations” to encourage hiking during cooler hours.

Excessive heat watches are declared by the National Weather Service in Phoenix. The agency posts a color-coded heat risk chart on its website based on temperature forecasts for that week.

An NWS employee told Cronkite News that it is difficult for meteorologists to predict how frequently heat watches will be issued, due to such factors as “moisture in the air from the ongoing monsoon season.”

The number of days when temperatures top 105 degrees in Phoenix has been on the rise. In 2020, 90 days reached or exceeded 105 degrees, up from 75 days in 2019 and 72 in 2018.

Regular hikers of the targeted trails voiced concerns at Tuesday’s board meeting, arguing that they’re being penalized for the mistakes of inexperienced hikers – many from out of town.

“This is a challenging hike as is, so if you aren’t a hiker then try something a little bit easier because for the people that are here on a regular basis this isn’t fair,” said Caitlin Walker, who frequently hikes Camelback. “This is our space, our serenity.”

The Phoenix Parks and Recreation Department recommends that hikers watch the weather, stay hydrated and stay on designated hiking trails.

The pilot program has started.
