Grand Canyon's South Kaibab Trail.

Three hikers died while attempting trails inside the Grand Canyon in recent days.

On June 12, a 72-year-old man died while hiking on the South Kaibab Trail.

On June 16, a 67-year-old man and 68-year-old woman were also found dead with signs of heat illness on the North Kaibab Trail. Their deaths are under investigation.

Despite the rapid response and aerial support, all three hikers were deceased once medical staff arrived.

From now until August, temperatures inside the Canyon can exceed 110 degrees during midday. The South Kaibab Trail is especially dangerous this time of year due to the intense heat, minimal shade and lack of water sources.

The National Park Service is urging visitors to pack plenty of water, seek shade and avoid trails between 10 a.m. to 4 p.m. Rescue efforts may be limited due to an increase in calls, limited staffing and helicopter flights during periods of extreme heat.

More tips for staying safe while hiking this summer can be found on the National Parks website.
