Driving into White Sands National Monument should be an easy process for any vehicle, no matter the size. Located in between Las Cruces and Alamogordo, taking Highway 70 will lead you straight to the visitor center no matter which direction you're coming from.
From Alamogordo, head west on US-70 for about 15 miles. The visitor center will be on your right and should be visible from the highway. If you're coming up from Las Cruces, you'll drive about 52 miles eastward on US-70 until you see the visitor center on the left-side. This is a very popular park within the area, so you'll see plenty of signs and traffic that indicate you're at the right place.
While you're on Dunes Drive, the first five miles are paved, and the last three are hard-packed gypsum. The road is very accessible - however, pay close attention to the weather, as it can drastically impact driving conditions in this park. Heavy rain or snow can make the road slippery, and it may be harder to spot ice on the road. Additionally, if there is a dust storm, avoid driving at all costs. Finally, do a quick check online or with a ranger to see if US-70 and the park are open - if there are missile tests going on, roads may be closed for safety.
