Castle Dome Mountains

Location: Between Quartzsite and Yuma, east of Hwy 95 in the Kofa National Wildlife Refuge.

Difficulty: Moderate.

Description: Travel through rugged parts of the Kofa National Wildlife Refuge. Perhaps you’ll catch a glimpse of some of the abundant wildlife, which includes desert bighorn sheep, mule deer, coyote, cottontail, bobcat, fox and golden eagle. Visit a cave once inhabited by Native Americans. Cross rocky McPherson Pass through the Castle Dome Mountains. Hike to well-preserved cabins at Big Eye Mine. Stop at the Castle Dome Mines Museum and learn about the area’s extensive mining history. Starts as a easy washboard gravel road but changes to single lane with minor obstacles. Mostly easy except for one moderate spot at McPherson Pass. This spot requires good articulation and high ground clearance. Suitable for aggressive stock SUVs. This trail crosses many miles of hot desert. Carry plenty of water and travel with another vehicle.

Time & Distance: About 54 miles. Allow about 5 hours on the trail plus traveling time. Add extra time for the uphill hike to the Big Eye Mine.

Trail Conditions: U.S. Fish and Wildlife Service, Kofa National Wildlife Refuge. Call (928) 783-7861.

Get yourself and your TOY ready for the trip: Make sure both you and your vehicle are ready for your next adventure.

Before you venture out on your offroading trip you need to make sure you are prepared for emergencies. Even if nothing happens to you or your vehicle, you might come across someone who needs help. Short of always having your full-on Bug-Out-Bag with you, you should at least have some basic emergency items. It might seem obvious to some, but you should get yourself a tool box with appropriate tools and leather gloves, good first aid kit, fire extinguisher, set of jumper cables, emergency blankets (stored in heavy plastic bag – both are useful), flashlight, tow strap and some extra water. I would also suggest a recovery strap, a military folding shovel, heavy duty garbage bags, and a hand crank self powered weather radio. These items are not expensive, but they just might save your day.

Another thing you should definitely do before you leave is to save Joe’s number in your cellphone in case you find yourself in need of recovery in the middle of nowhere. Joe is the owner of Arizona 4×4 Off Road Recovery and has become a real hero to many in the Arizona offroad community. His number is (602) 697-8306.
