Looking for a National Park Week adventure? Photographer Jonathan Irish recommends Guadalupe Mountains National Park in Texas. Besides stunning mountains and rolling plains, sunset over the sand dunes is quite an experience. “You aren’t really sure what to expect until you see these striking dunes unfold on the horizon. I was lucky enough to see a beautiful sunset here, which took my breath away. The hike back to the car, by myself in the dark with coyotes howling all around, was quite interesting.” Photo courtesy of Jonathan Irish.
