Cave Rock Spring Road is a remote, roughly 12-mile one-way dirt 4WD spur in the Nevada Triangle portion of Death Valley National Park (and adjacent public lands), near Rhyolite and the Bullfrog Hills.
Trail / Road Description
Access begins near the Bullfrog turnoff on Rhyolite Road (between Nevada Highway 374 and the Rhyolite ghost town). The route winds through the western Bullfrog Hills into a large wash, where it splits. The south fork is Cave Rock Spring Road; it continues past the Hooligan (Happy Hooligan) Mine area and ends about 0.25 mile below the spring itself.
- Distance: Approximately 12 miles one-way to the end of the road near the spring (the final short stretch into the spring area is closed to vehicles).
- Conditions: Unmaintained dirt road with sandy sections in the wash. High-clearance 4WD is strongly recommended. Road conditions change with weather and flash floods; check with Death Valley National Park or the BLM before travel.
- Terrain & scenery: High-desert hills and washes with sparse Great Basin vegetation (sagebrush, rabbitbrush, golden cholla). The road offers solitude, views of the Bullfrog Hills and Grapevine Mountains, and a tangible sense of the remote mining landscape that surrounded Rhyolite. Elevation near the spring is roughly 5,100–5,200 feet.
- Key stops: The Hooligan/Happy Hooligan Mine (about 10.9–11 miles in) has mine dumps, sparse wood ruins, and debris. Beyond it, stone foundations appear before the road ends short of the spring.
- The spring: Cave Rock Spring is a small seep surrounded by a dense thicket of desert broom. It is not a reliable potable water source today and is often affected by wild burros. The name likely refers to the rocky setting of the seep.
This is remote backcountry. Carry ample water, be self-reliant, respect historic artifacts (leave them in place), and be prepared for changing conditions. It does not connect through to other major routes.
History of Cave Rock Spring and Its Connection to Rhyolite
Cave Rock Spring sits in the broader Bullfrog Mining District on the east slope of the Grapevine Mountains / Bullfrog Hills area, roughly 10–12 miles west of the Rhyolite / Bullfrog vicinity.
Rhyolite exploded into existence after prospectors Shorty Harris and E. L. Cross discovered gold in 1904, launching the Bullfrog rush. By 1907–1908 the town briefly supported several thousand people (estimates range up to ~5,000–10,000 in the district) with banks, a stock exchange, railroads, electricity, and other amenities. Water was the critical limiting resource in this arid country. Early on it was hauled by wagon at high cost ($2–5 per barrel). Multiple companies later piped water from various local springs into town.
Cave Rock Spring itself was a minor seep rather than a primary long-distance piped source for the main Rhyolite townsite (those came from springs such as Indian Springs and others). It formed part of the network of small springs and seeps that supported mining, wood camps (including nearby Mexican Camp), travel, and livestock across the Bullfrog Hills during the boom. Nearby, the Happy Hooligan (Hooligan) Mine was discovered in May 1905. By early 1906 it had its own camp with a boardinghouse, blacksmith shop, and store-saloon; a road was built and the property was heavily promoted. The high-grade surface ore was quickly worked out, and the mine was abandoned by the end of 1907. Only dumps, sparse ruins, and debris remain.
After the Rhyolite boom collapsed (Montgomery-Shoshone Mine closed in 1911; power cut by 1916; the town essentially abandoned by the early 1920s), remote springs like Cave Rock continued intermittent use and later became watering points for wild burros. The road and spring today preserve a quiet link to the water-scarce realities of the short-lived Rhyolite-era camps and minor mines that surrounded the famous ghost town.
Note: Rhyolite itself lies just outside the national park boundary on mixed federal and private land and is managed primarily by the BLM. The Nevada Triangle (including this road) is within Death Valley National Park. Always verify current access and conditions, as flash floods and other factors can affect remote dirt roads.
