Set in southeastern New Mexico, Roswell provides easy access to the mountain resort of Ruidoso and the fishing and water sports at the Bottomless Lakes State Park. But if you’ve come to Roswell, you’ve really come for one thing: aliens. In 1947, reports of a UFO crash and the recovery of alien bodies near Roswell started a debate that’s still raging today. Whether you believe the UFO is a government cover-up or a hoax, the story is well played up on the main street of Roswell in fun and funky shops filled with books, t-shirts, sunglasses, toys, and more, all featuring aliens. There’s a museum and an out-of-this-world coffee shop. Even the streetlights are painted with alien features and glow a bit green after sunset. While Roswell plays to the alien hunters, it also offers a more serious museum with displays about rocket scientist Robert Goddard, art, and artifacts, as well as hotels and restaurants for those just stopping by.
