Eldorado Wilderness is a 31,950-acre property in the Eldorado Mountains. Most of the property is a maze of jagged volcanic peaks, wide washes, narrow drainages and deep canyons, a continuation of the countryside shown in Black Canyon Wilderness to the north (the two wilderness areas are separated by a power line right-of-way). There was a time when the Eldorado Wilderness saw significant mining activity.
Vegetation is scarce and what little there is is a mix of creosotebush, scrub oak, ephedra, clump grasses and cactus. However, there is enough vegetation and water around to support a few desert bighorn sheep, some bobcats, mountain lions, lots of jackrabbits, a few coyotes and the omnipresent rattlesnakes, lizards, scorpions, tarantulas and chuckwallas. There's even a few desert tortoise around.
Eldorado Wilderness is mostly managed by the National Park Service as most of the property is within the bounds of Lake Mead National Recreation Area, however, that small part of the property on BLM land is administered by the Bureau of Land Management.
