We will be in Moab starting next Saturday (May 19 ). We'll have 4 days, 5 nights there. The first full day (Sun/May 20) is expected to by 97. I realize it is a dry heat! so not like 97 in Ohio when it is humid and feels like 110. But that is still HOT to me. Wondering if one of these would be a better choice given the temperature - Arches - delicate arch hike; Arches - Devil's garden area; Canyonlands - Island in the Sky; or ATV tour around Moab. We'll stay on Ohio time and be up and out early regardless of what we choose to do. Any thoughts on which might be "cooler"? Looks like it will be in the 80's the other days we will be there. And here I thought I would beat the heat by going in May vs June!
