We leave soon and without plans will be wandering Texas, NM, Arizona, Southern Utah and Colorado. Not our choice time of year, but its the window we're given.
We have other reasons to be as far south as New Orleans, so our trip starts and ends there.
We know what we're doing for about two weeks of the six. Cajun country, San Antonio, Big Bend, Carlsbad, White Sands.
Beyond that, we'd love to do some moderate boondocking (travel trailer) in the desert.
Main question....Where are the isolated spots of high elevation in these states that can give some relief to the heat?
Not asking for anyone's honey hole, but specific places of "cooler weather" in those states would be very much appreciated. Of course Colorado has obvious options, but what about those other states?
