A summer hike through Utah’s red-rock country can become dangerous much faster than visitors expect, especially with recent high temperatures. Rangers at two popular national parks have already handled nearly two dozen heat-related emergencies this year.
According to the National Park Service, rangers responded to 23 heat-related search-and-rescue incidents at Arches and Canyonlands national parks through Aug. 4. Eleven occurred at Arches, while the other 12 happened at Canyonlands.
Park officials are sharing the numbers because they believe many of the emergencies could have been prevented. Temperatures in southeastern Utah regularly rise above 100 degrees during summer, and the exposed landscape provides limited shade.
The official warning explains how intense sunshine, low humidity and high elevation can quickly cause dehydration or illness. The parks also shared the guidance on social media to reach travelers planning late-summer visits.
Rangers Recommend Avoiding Midday Hikes

The official Arches National Park Facebook post outlines the risks and precautions visitors should take during extreme heat.
Rangers recommend planning hikes during the cooler morning or evening hours. Visitors should avoid strenuous outdoor activities between 10 a.m. and 5 p.m., when heat and sunlight are especially intense.
When conditions become uncomfortable, travelers can choose a shorter trail, take a scenic drive, attend a ranger program or explore a visitor center. Everyone should adjust plans based on the forecast, their physical condition and the abilities of other people in their group.
Hikers Should Carry Several Liters of Water
For front-country hikes (only a few miles from facilities, if needed), the parks recommend carrying two to three liters of water per person, while backcountry travelers should bring at least four liters each.
Water is available at the Arches visitor center and Devils Garden Campground. At Canyonlands, visitors can refill at the Island in the Sky and Needles visitor centers or at the Needles Campground.
Rangers advise drinking regularly instead of waiting until thirst becomes overwhelming. Groups should turn around once half of their water supply has been consumed, ensuring that they have enough for the return trip.
Salty snacks can help replace calories and electrolytes lost through sweating. Lightweight, loose-fitting clothing, a hat and frequent breaks in shaded areas can also reduce the risk of overheating.
Visitors Should Recognize the Warning Signs of Heat-Related Illness
The Mayo Clinic warns that possible signs of heat-related illness include dizziness, weakness, headaches, nausea, muscle cramps, confusion and excessive sweating. Someone experiencing symptoms should stop moving, find a cooler location and drink water.
Visitors should call 911 if symptoms become severe or continue to worsen. Children and pets should also never be left unattended inside a parked vehicle, even for a short time.
