Limbo WSA Description Kumiva Valley sits at the heart of a massive OHV trail network that stretches across western Pershing County. This expansive system connects a variety of popular riding areas including the Black Rock Playa, Granite Range, Buffalo Hills, and Rye Patch State Recreation Area. To the northeast lies the rugged Lava Beds mountain range, surrounded by OHV-friendly roads. On the northeast edge of the network you’ll find the ghost town of Sulphur, where a few ruins remain along with informational kiosks and markers. A lone historic cabin still stands in the center of the site with plenty of parking on the wide dirt roads. Gerlach serves as the closest town for food and fuel, with a small market located 7 miles south of town on State Route 447 near Empire. Farther south along the same highway, Nixon and Fernley offer more services and amenities. Don’t miss the popular Trego Hot Springs, located roughly midway between Sulphur and Gerlach.
