【February 24 2014】July to September is thunderstorm season at Grand Canyon National Park and the surrounding wilderness. A count taken from 1997 to 2000 found that lighting struck somewhere in the canyon an average of 26,073 times per year. As long as visitors are in a safe place – preferably indoors or at a spot where the span between flash and thunder is longer than 30 seconds – the show can be spectacular.Explore breathtaking Gallery from the HuluTrip homepage over the past 5 years..
