Combination single track & fire roads through old & new growth w/3200 feet elv. Cont. from "Trailhead" ...Stay straight as first main road comes in from left, Stay L or straight as second road comes in from right, Take the steep left off main road. At the top of this climb is a clearing, look to left by downed log for a single track down to a gravel road, go L and climb to the point the road levels out. Look to your R for another single track trail. Follow this trail to the top of hill and down the other side till it comes out at a junction of fire roads. Take the left road and head down the road till it "T's". At the "T" go L stay on main road for about 2 miles (if you go down hill to main JCT, you missed it) and take a L onto short trail that goes up, at top take L (Stick in Your Eye). Follow this trail (including 30 yards of gravel at top) down to 760 rd, cross over and continue on trail down to 760 again, go R and follow down to 700, then down to car. Trails are muddy in winter & spring. Horses on roads, not trails.
seems like there is a lot to explore up here. will go again for sure.
There are a number of different ways to the top of McCulloch Peak, all different and all interesting, some more than others. You can approach from the Oak Creek Station side, ascending by road all the way. You can approach this way, ascending via Uproute and then heading off into the woods on the left, heading almost straight up through the woods, reaching a forest road at the top and then winding around to the top. Expert mtn. bikers come down this way, though I'm not sure how. You can ascent from a parking lot off Sulfur Springs Road that follows the road all the way or you can take shortcuts through the woods. Get a trail map in any case, to make sure you can get back to your starting point.
Take water and some food / energy bars. This is a longish hike with some steep parts.
If I were planning on doing some long hikes elsewhere this would be a great peak to practice on as it has some steep parts and is a failry long hike, about 9 miles (14 km).
This is also a great mtn. bike peak. You can take many of the same routes as you would on foot, though some, esp. the one I mentioned earlier off Up Route, likely would involve pushing your bike uphill a lot. It would be a screamer coming down, assuming you have the skills.
Oh yes, the views are pretty good, though if you want good views, stick to Dimple Hill and Marys Peak.
First off I'd like to mention that the trail category should not be labeled as "loop". Matrix is a much more fitting title. There are as many ways into the trails as there are out. The bonus to these trails is that all the parking is on actual mapped roads instead of logging roads and at every parking lot is a map of the trail system. I went out and got lost for three hours and it was glorious. The climb to Dimple Hill is very scenic and a great exercise, the more advanced cyclist should grab a map and ascend the big butte. I can't remember the name but it's over 2100 ft. elevation. The thing to be mindful of is when to enter the single track. Climbing up a descent trail can be a major pain but if you enter at the right path prepare your cheeks for a permanent smile. The link is where I parked. I found it best to park at the farthest north parking lot since most of the trails would be south. I found it easiest to navigate while lost by traveling north.
