Santa Fe is at 7,200 feet making it considerably cooler than other spots in the desert southwest (Phoenix is 1,000 feet in elevation. Every thousand feet, the temps drop 3.5 degrees F. If you hike up from those elevations, early in the morning, you beat the heat until you’re on your way back down. But watch out for sun exposure – light colored long pants and shirts are safer than shorts with the intense UV at elevation.
I had a fabulous tip to Carlsbad Caverns by being first in line one morning for a ticket, hurrying on over to the natural entrance (versus the elevator), thereby being near the front of the line (of 20 or so) as they ranger gave a safety talk and then let opened the gate. While others oooh’ed and aaah’ed around the large natural entrance, I took long strides down the path and had the cave seemingly all to myself for almost an hour before I saw any other visitors coming the other way. Similar to leaving for Half Dome at 3 am and being on top before dawn, all by yourself.
