Awesome views! Fairly intense once you get on to tolman trail, but eases up once you hit south trail. Lots of cows, a pond, and a creek side walk on the other side of the loop. We started at 7:30am and finished around 9:30, with a couple breaks. Glad we started early as when we got back to the parking lot it was almost full(it was Sunday). We picked up some empty water bottles and other misc garbage. I’d recommend it. Our record says it was 5 miles.

Hiked 5/5/18. The hills are still green,grasses are tall and thick. Mustard on sections of the trail were up to about 8_9 feet tall. I'm sure this will all change in the next week or two. I was surprised to find a small grove of trees that included redwoods and Sequoias. Some owner at some point must have planted these. I was thinking I didn't see much wildlife then saw a bobcat near the top of Tolman. Beautiful bay laurel tree at the very top. Veins were great of the bay.

Nice enjoyable trail! STEEP in the beginning of the trail, but it’s worth it once you see the stunning views... there’s even a bench on the top for you to rest.

Tough trail. But amazing view at the top.

Matt D's review basically covers it.. nice trail, would do it again

Beautiful hike. Definitely do when it's still green but it's beautiful all year round.

Pretty cool trail! Partial shade/sun and dog friendly! Some hills but nothing too bad.

Well this was a pleasant surprise. I've done a handful of hikes in the Garin and Dry Creek parks and found them to be rather meh. Typically in this area you're walking up a steep hill with no shade or through a cow pasture. And yes, once you reach the top of the ridge, the views are nice, but you can get that all over the Bay Area without having to constantly dodge horse or cow poop. I would prefer to go on hikes where I don't have to negotiate a herd of cattle.

But this trail was different and by far my favorite so far in the area. The loop was mostly shaded, which was much appreciated on a warm sunny day. And the tree line that you hike through is scenic. There was still some evidence of horse traffic, but I didn't encounter any cows. I went in the evening on a weekday and by the time I got onto Meyers Ranch trail to head back to the parking lot, the hills were keeping me in the shade there too.

The Pioneer trail was really nice. I had passed it before on my way up High Ridge, but this was my first time on it. No bikes allowed on that trail btw as it is very narrow.

I'll probably go back at some point. It's good for a short hike during the week when you get off work as it isn't overly strenuous and you can knock it out in less than an hour. And I like the May Rd. staging area - you don't have to pay to park and you don't have to climb up a big hill to get to it (like you do at Garin).

A challenging trail that offers some shaded areas along the way. Wonderful views at the top!

It was a good trail, not popular so not that crowded. Loved the view from top !! And little plane crash history was good to know.

Not crowded at all. Did this trail early morning around sunrise. Has beautiful views. Kid-friendly.

It's a beautiful hike through meadows, riparian forest, shaded canyons, and a panoramic view of the bay. What a nice discovery.

Parking at Tamarack (and nearby) is now prohibited for non-residents. Park at the entrance on May Rd and join the trail from there. It was not a bad hike. Get there early in the summer before it gets too hot.

This isn't 5 miles. It's at least 6. My GSP tracker said 6.5.

And I would not call this easy for beginners. The first and last 1.5 miles or so are flat, but that middle few miles is pretty steep for newbs. 1-5 I'd give the whole thing a 3. 1 being totally flat. 2 being slight elevation gain. Nice views. Cool if you don't feel up to hiking Mission Peak.
