  Likely In-Season!
Yoas Mountain is a high point southwest of Elephant Head and northwest of Little Elephant Head. Note, that the mountain peak is lower than the trailhead elevation, so there's a good amount of downhill and then uphill for this hike. The hike involves roughly 2.8 miles of well-maintained trail and sections of 4x4 road, and about 1 mile of bushwhack which isn't bad if you stay in the canyon, away from the catclaw and are able to navigate around a lot of ocotillo on the various hillsides.

Start off walking up the Elephant Head Bike Trail #930. This trail is fairly well-maintained and easy to follow. After roughly 1 mile you will reach a junction. The trail going up is the Quantrell Mine trail and the trail going down is the Chino Basin Trail. You will take the Chino Basin Trail down which is an old 4x4 road. Take this road downhill and after hiking a total of 1.7 miles you will see a sign on the right that marks the old Elephant Head Mill Site. The sign references some old adobe walls at this location, but as of November 2022, I looked around very carefully but didn't see any walls or adobe structures here. About 7 or 8 years ago, I remember seeing some adobe walls when I hiked in this area before. I'm interested in knowing what happened to those walls. Anyway, continue walking down the 4x4 road. Within a few minutes, you will see a metal gate in this trail which prevents vehicles from driving up but hikers are allowed the walkthrough. After hiking a total of 2.7 miles from the trailhead, turn left on a road junction and follow that for about 500 feet. After that, you will need to bushwhack west about 50 feet up in elevation so that you can see Yoas Mountain. From there you should have an idea of where you need to hike to summit this peak.

Continue southwest and go higher in elevation as you hike closer to Yoas Mountain. Don't drop down to the canyon quite yet because there's a big drop off in the canyon at this point. You can drop into the canyon anywhere south of this point. The canyon is fairly open and easy to follow. It will be much easier to hike in this canyon as compared to the hillside that is south and east of it. That hillside has a lot of catclaw bush and densely packed ocotillo. Follow the canyon for about 500 feet. To the west will be a high point which is part of the ridge going further west toward the highest point on Yoas mountain. Climb up the hillside and stay left of the rocky high point. During this climb, you will see a lot of densely packed ocotillo that you will be able to weave through. Once you reach the top of the curved ridge it should be easy to see where you need to go next. Keep following the ridgeline staying close to the top and you will eventually make it to the top of Yoas Mountain.

At the peak, there were some great views of both Elephant Head, to the northeast, and Little Elephant Head, to the southeast. You should be able to see Mt Wrightson and Mt Hopkins in the distance to the east/southeast. You'll see a registry at the top under a pile of rocks.

On the way down, hike down to the same canyon you came up from. Once in the canyon, if it is dry, you could follow it down to the point referenced above until you see a 50 or 60-foot drop-off. From here there are some nice photos. Next, you'll need to hike back up the canyon and stay left to go around the cliffs. Then, you'll need to descend northeast toward a lower saddle. From that lower saddle hike East until you see a road below. Take that road north until you reach the main Chino Basin road. Make a right and walk up the hill roughly 1.5 miles to the junction. Turn right and follow the Elephant Head Bike Trail back to the parking area.

My uploaded route also shows some exploration I did on the lower part of the Chino Basin Trail and FS 4073, before heading back up to the trail junction. FS 4073 is a pretty rough road, but with a high clearance 4x4 vehicle, it may also be possible to start this hike from somewhere along this road.

    High Clearance possible when dry

    To Elephant Head (arbitrary/unofficial) Trailhead
    From anywhere in Tucson, head south to I-19. Take I-19 south to exit 56 (Canoa). Take the east Frontage road south for three miles to Elephant Head road. Follow Elephant Head for about one and a half miles and turn right onto Mount Hopkins road. Take Mt. Hopkins road for 5.5 miles and turn north onto FSR 183, which is marked by the standard vertical FS road marker. Follow FSR for about two and a half miles until it approaches the basin of Agua Caliente stream. A large sign to the right of the road states "Dead End 2 Miles." Park here under the plentiful trees. Walk back down FSR 183 in the direction you just came for about 100 meters until you encounter the junction with FSR 930 - The Elephant Head Trail.

    2015-12-20 philmacduff writes: High clearance vehicles recommended on FSR 183. The road becomes impassable to cars with less than 9" clearance (even when dry) approximately 200m from the trailhead. Up until this point, with careful driving, it is doable with a decent 2WD car. You should be able to find a spot to park on the side of the road somewhere prior to this point. Be prepared to back down the dirt road if needed. Also, note that FSR 183 is not marked well from Mt Hopkins Rd as FSR 183. There is a small sign about 40 yards down the dirt road, but nothing else was visible from Mt Hopkins Rd.

    2014-03-03 andrewbares writes: Another rougher 4x4 entrance exists, on FR 4073. Same as above, exit 56 from I-19 and turn left on Elephant Head Rd. However, continue on Elephant Head Road and simply keep straight (turns into Hawk Way). Eventually, it'll turn into a dirt road that heads southeast. Continue on that dirt road. You'll reach a gate on your left, but continue straight (goes directly south now). Finally, you'll reach another gate at the end of a big open parking area, and you'll go left through that gate. Very soon after, you'll come to a 4-way intersection... turn right onto FR 4073, which has a marker a little way down the turnoff. This is where the road starts getting rougher. You'll cross through the wash and continue heading south for the rest of the drive. Stock 3rd generation 4Runners (1996-2002) will be perfectly fine. No rear lockers are needed. I recommend 9.5" of ground clearance. Low gears aren't even needed. It's just a rocky trail. At the very end, it will get quite narrow (and eventually turns into an ATV trail) so park where you feel comfortable.

    From PHX (I-10 & AZ-51) - 2 hr 37 min (155 miles)
    From TUC (Jct 1-10 & Grant) - 58 min (45.4 miles)
    From FLG (Jct I-17 & I-40) - 4 hr 40 min (298 miles)
    (Trailhead is generic)
