How to get there
Chemehuevi Mountains Wilderness lies 10 miles southeast of Needles, California, along U.S. Highway 95 in San Bernardino County. Trampas Wash provides hiking access from the west into the interior and toward the Colorado River. Obtain area maps from BLM field offices in Needles or Lake Havasu City and confirm the approach before driving. The Needles Field Office is at 1303 South U.S. Highway 95, Needles, CA 92363; telephone 760-326-7000.
- U.S. Highway 95 approach
The highway is the named approach corridor along the wilderness near Needles. Use a BLM map to establish a suitable entry location and the wilderness boundary; this is not a specified trailhead.
- Trampas Wash — west-side hiking access
Trampas Wash cuts through the mountains and offers the easiest hiking access from the west into the wilderness interior and toward the Colorado River. Confirm the ground approach with BLM rather than assuming developed trailhead facilities.

A desert range opening toward the Colorado River
Chemehuevi Mountains Wilderness protects 85,840 acres in San Bernardino County, California, southeast of Needles. Designated in 1994, it is managed by the Bureau of Land Management. The mountains form a horseshoe opening east toward the Colorado River, enclosing a central valley of rolling hills with cholla, ocotillo, and occasional agave. On the western side, pale granite peaks rise above creosote and cactus-covered bajadas. Toward the river, red and gray volcanic spires and mesas change the character of the landscape. This is a place for hiking and solitude in varied desert terrain, rather than a single prescribed outing. Plan around the terrain you intend to explore: the broad washes, interior hills, and rugged peaks offer distinctly different travel conditions.
Planning a wash-based hike
Trampas Wash is the clearest starting point for planning a hike into the range. The twelve-mile-long wash cuts through the mountains and provides the easiest hiking access from the west into the wilderness interior and toward the Colorado River. That length describes the wash, not a defined round-trip itinerary. Red Rock Wash also crosses the wilderness from west to east; both washes have broad, sandy courses lined with trees. Use a map to choose an objective and turnaround rather than assuming either wash is a signed trail. Maps are available from BLM field offices in Needles, California, and Lake Havasu City, Arizona. Carry water for the full outing, sun protection, and navigation tools. Springs and seeps occur here, but do not build a water plan around finding usable water.
Wildlife and wilderness travel
The meeting of the Sonoran and Mojave Deserts, together with influences from the Colorado River and eastern Arizona, supports a varied desert community. Bighorn sheep, desert mule deer, wild burros, and coyotes occur here, along with jackrabbits, kangaroo rats, roadrunners, quail, and lizards. The southwestern portion is especially important as critical habitat for the threatened desert tortoise. Give animals space, leave plants and natural objects in place, and keep travel and camping on durable surfaces. Pack out waste and minimize campfire impacts. Motorized equipment and mechanical transport, including vehicles and bicycles, are generally prohibited within federally designated wilderness. Keep vehicle access separate from the hiking portion of a visit. Confirm current access conditions and applicable regulations with the BLM Needles Field Office before setting out.

Route options
- Trampas Wash exploration12 miles long (wash length)
Follow the wash into the mountains from the west, choosing a turnaround appropriate to conditions and the group. The wash continues toward the Colorado River. Its stated length is not a measured round-trip hiking route.
- Red Rock Wash exploration
Red Rock Wash crosses the wilderness from west to east along a broad, sandy, tree-lined course. Treat it as a map-planned exploration rather than a defined trail itinerary; establish an entry point and turnaround before departure.
Sample itineraries
- Trampas Wash day hike · 1 day
Explore part of Trampas Wash from the west side, returning the way you came. This is the easiest hiking approach into the interior. Set the turnaround by conditions, water and daylight; the wash's stated twelve-mile length is not a day-hike distance recommendation.
- Two-day desert landscape sampler · 2 days
Plan separate day hikes in Trampas Wash and Red Rock Wash, confirming approaches with BLM maps first. Compare sandy washes, cactus-covered terrain and surrounding peaks. Choose out-and-back objectives suited to conditions rather than assuming a connecting loop or a maintained trail.
Seasonal conditions
Spring
Spring
Plan for exposed desert hiking and changing temperatures. Carry water rather than relying on springs or seeps. Adjust objectives to the forecast and protect cactus-covered terrain by choosing durable walking surfaces.
Summer
Summer
Treat heat and sun exposure as major planning concerns in this arid landscape. Keep objectives conservative, avoid the hottest conditions and carry sufficient water for the full outing.
Fall
Fall
Do not assume the desert has cooled enough for a long hike. Check the forecast, keep a water reserve and allow enough daylight for slow travel through sand and rugged terrain.
Winter
Winter
Prepare for cold conditions as well as daytime sun. Carry insulating layers and check the forecast before entering the mountains. Shorter daylight makes conservative turnaround plans especially useful.
