Hike Maguire Peaks Loop and you might be lucky enough to see the herd of Tule Elks. Located in the northwest corner of Sunol Regional Wilderness, Maguire Peak is one of the least visited area in this popular hiking ground. This easy 4.7 miles hike provides great solitude and nice views on San Antonio Reservoir for hikers. If you are lucky enough, you might be able to see the herd of Tule Elks wandering somewhere near the reservoir. To get to the trail head, drive 0.7 miles on Welch Creek Road from the junction with Calaveras Road until you see the gate with a small parking lot on your left side. The gate is marked SO12.

Great hike. Quiet. Amazing views from the peak. Mainly in good visibility day.

Awesome views. Moderate elevation gain.

Do not try and use the Lower access area. It is closed. There used to be a gate, but now t is just barbed wire. Rather is the upper McGuire loops access point - around another half mile up Welch creek on the left.

Started this hike from the Sunol Visitor Center and up the HayField road, then follow the signs for Maquire Peaks loop. I wanted to do more that the 5 miles from there, and this was a nice add to make a 12 mile hike.

I saw Quail along with baby chicks, Turkeys and their baby gooblers, turkey vultures, hawks, woodpeckers.

I will note that I didn't believe the comment about the Tule Elk, but found that there ARE sighings in this area. What a treat it would be to see one though.

I added a bit more on the way back to the visitor center by cutting over to the Indian Joe trail for a bit of stream and shade walking. I ended the hike at 2pm and at 100~f.

Great trail, but be sure to wear high hiking socks! Grass sticks to boots and socks and is hard to unattached. Views of the east bay area worth it though.

As of March 2017, the first part of this trail is washed away due to the rain. I do not believe these other reviews are recent. The first spur of this route is completely unmaintained. You need to crawl through a barbed wire fence to get to the trail. There is very limited parking. I think other reviews are mistaking this for a different starting point.

Perfect weather, everything was beautiful and green with lots of water. Trail was muddy but we had a great time!

From Calaveras to Welch Creek Rd, I started at the trailhead entrance on the left. Welch Creek Rd was frighteningly narrow for my comfort zone, as well as steep. It is just about a mile of fire road to get to the loop trail. Much of the lower trail was soggy due to recent rain, but wide enough to be able to scramble to avoid any ankle deep areas. The peak was gorgeous on this mostly sunny day. The various birds, the greenery, and the views were delightful. I was hoping to see elk down below but no such luck this time. In all (6 miles for me) this took 2 hrs, not another person in sight.
