One of the world's largest solar observatories is near Sunspot, 20 miles south of Cloudcroft. Though it's primarily for scientists, tourists can take self-guided or guided tours. The high and beautiful Sunspot Scenic Byway leads to the site, with the mountains to the east and White Sands to the west. From Cloudcroft, take Hwy 130 to Hwy 6563 – and fill your tank before you set off.
