Start your trip in Sin City, with its neon lights and nonstop debauchery, before escaping to the desert.

If you go a little beyond the Extraterrestrial Highway, you'll find a great space-themed gem: The Lunar Crater National Natural Landmark. Full disclosure: It wasn't formed by a UFO, or even by a meteor. The volcanic crater got its name because it looks like the surface of the moon. You might imagine homesick Martians stopping by the barren desert formation to see some familiar landscapes.

Right on Highway 95 is the Death Valley Inn, a modest motel that's just a few minutes' walk to downtown Beatty, Nevada. This hotel is less than 10 miles from Death Valley National Park, which experiences quite a few otherworldly phenomena, including the "Sailing Stones," which are rocks that mysteriously move on their own. The motel offers an outdoor pool, a whirlpool, and barbecue grills, as well as an onsite RV park.

Most notably, Area 51 is just off the route, and it's a mecca for UFO enthusiasts. As a warning, it's illegal to trespass on the land surrounding the top-secret base. But, there are trails to hike that will give you a good overview of the iconic hotspot. The trail to the top of Tikaboo Peak is the most popular.

Once you reach Hiko, Nevada, pull over at the Alien Research Center, which is less of a scientific research center and more of a gift shop. Browse the UFO and alien-themed souvenirs, and as well as the actual research area. Take a photo with the giant silver alien out front.

Next, you'll come to the Little A'Le'Inn. This is one of the most famous stops along the drive. The diner is adorned in alien kitsch, and you can browse the gift shop for UFO-themed merchandise. If you chat up the waitstaff, they'll probably tell you about various alien encounters along the road, the craziest conspiracy theorists they've had stop by, and maybe, if you're lucky, the best way to check out Area 51. Also, do yourself a favor and order the Alien Burger.

If you're really dedicated to seeing some UFO action, hike to the top of nearby Tikaboo Peak—it's the only legal place to view Area 51, which is surrounded by mountains virtually on all sides. The steep hike will take about two hours, so it is best to come prepared with water, flashlights, and other supplies.

If you're in the mood for extraterrestrial camping, pull in for the night at Lower Pahranagat Lake Campground. It's in a remote and isolated part of the state, which is perfect for uninterrupted UFO-spotting and stargazing.
