Castle Dome Peak is an off trail trek in the Kofa Wildlife Refuge north and slightly east of Yuma, Az. It's not a technical peak but you had better have good route finding skills, endurance for endless bouldering and scree surfing, bushwacking, and there is some exposure on the route.
My partner and I got an early start, slightly after 8:00 after trying to find the TH in the dark, not recommended. The wash is wide and finely graveled, with a little vegetation to dodge. It is very scenic right from the start with the towering dark and reddish rocked spires enclosing the area. Keep an eye out for Bighorn Sheep here. The wash winds around. Some cairns show up, there are several ways to leave the wash. Castle Dome is right in front of you here. Your goal is to get to a prominent small spire next to the main rock massiff. We decided to almost head the wash, very narrow, constant boulders and lots of catclaw.
From the saddle looking over into Kings Valley and back down our route, it was surprising to see how much we had gained in elevation already.
Here we climbed several ridges, skirting large rock outcroppings. Its rough, somewhat loose and very steep. We gained the "cactus filled saddle" just below the spire. Here you will see a faint trail that will lead you to the spire base. Now you have a choice of a couple of Class 3 short pitches, one very easy we descended, one more vertical and about 200+ feet exposure.
We climbed that one, a bit tight under some boulders. We didn't have a rope and it was a bit scary for me. Next you will see cairns skirting along the cliffs that then lead you up over sharp jagged rocks. A fair amount of exposure here but the rock is solid and footing good.
The summit is elongated and undulating, you have 360 views that are tremendous. The peak register is in an ammo can on a prominent rock outcropping to your right when you gain the peak. This is a training climb for the Golden Knights team, so quite a few military sign ins up there. Looks like light use overall.
The downclimb was worse than the up, lots of scree, we both sat down three times. We cliffed out twice; you either have to do a traverse at the base of the main peak across or go down some ridges almost going away from where you want to go to the wash. In the middle are sheer unclimbable cliffs unless you have a 150+ foot rope and climbing gear.
We descended a lovely dry waterfalled chute, it dropped off and we climbed out to continue down a drainage to the wash. We couldn't have timed it better for weather, cool, a little wind, and although hazy on top, it started to clear as we descended. The next day blew like heck so I headed home. We did some other exploring in the area. Really gorgeous once you get off the beaten path.
To hike From Yuma take hwy 95 north/ from Quartzite take the same hwy south. 35 miles north of Yuma turn right on the Castle Dome Mine road (left if coming from the north). This is a good graded dirt road. Drive north to the mining museum about 10 miles, past it about 5 miles on a narrow washed out track. Castle Dome will be in front of you and you will contour around the foothills to the northwest side. Look for a wide wash with a no vehicles sign in front of it after coming around a curve. Ample parking in the wash.
