One unpaved road (the Lunar Crater Back Country Byway) passes by the crater, and the usual approach is from the north, starting from US 6. The junction is marked by a BLM signpost, from which it is a 8 mile drive to the crater's edge. The journey from the south is longer, lonelier and not signposted; this route begins from NV 375, 'The Extraterrestrial Highway
', along a gravel side track that heads northeast, 16 miles south of Warm Springs. The first stage is 10 miles along the track, across the flat expanse of Railroad Valley
, a typical Nevada basin with little to see apart from sagebrush, alkali seeps and, as the location is still at a relatively low elevation, occasional Joshua trees. A left turn at the first cross roads leads into the low hills that line the valley, the surface now less good - variously sandy or rocky - and enters the volcanic field after about 15 miles. Another left turn at the next junction leads to the crater and joins with the northern approach, where the road widens and improves.
