Our dog has a bad knee and sensitive paws, and the first 2 miles she went very slow. The third, more eucalyptus-forested last mile of the trail she had no problem and was all downhill.

This trail appeared shorter than advertised. The start of the trail is not well marked so it’s difficult to find the trailhead although once underway all other intersecting trails were readily identifiable. The flush toilets at the parking area were a definite plus. I would rate this trail as easy and not moderate.

It's a good beginner trail. Some good views.

Interesting trail done a long time ago.... Also did all the connector trails and parks south. You can go all the way to Chabot pretty easy. A couple of places where you walk on the street for a couple of blocks if you do.

Enjoyed this. Great place to take the dog. They are allowed off the leash. Will definitely be coming back.

Great hike, would do it again

Tried to do this loop on July 4 and the first section of the trail is currently closed due to “dangerous tree conditions” - hiked the half that was still open and it was nice.

Mostly very wide, exposed trails. Views are mostly nice... mostly of the valley, but some look out over the hills. Round Top Loop is mostly shaded and good for a short hike.

Good length and degree of difficulty. Nice variation in terrain.

Quick little trail with dogs on/off leash. Took my girl there and she did great, even as a shy dog. My coworker took his 15yr old dog and he did amazing for his age! Very easy trail that switches from paved path, to rocky dirt, to forest floor. Plenty of parking on a Saturday evening. Just wish there were more signs at each fork to tell us which trail was which. Still would love to bring the dogs back again!

This area isn't bad, but it's also not great. I think if you live in this area, this is a nice place to go when you want to get out and don't have a lot of time. I'm a bit further out, so I doubt I'll be back. The trails are okay, pretty moderately trafficked. You'll see hikers, bikers, and a good number of dogs (that are of leash). The views at the top along Volcanic Trail are also okay - they're a nice little bonus if you're just out here for the activity, but I wouldn't count them as a draw to come here.

Biggest issue: very limited parking.

Beautiful hike! Took Top Loop to Volcanic loop, with a detour to the frog ponds. Been seeing some rain so everything was a beautiful green with the yellow tree blossoms. Mostly flat with some fun scrambles up steep hillsides for some stellar views!

Just did this hike today; it was the perfect length for a nice Sunday stroll. I highly recommend doing it while the hills are green and lush from the winter rain (see the pics I uploaded). Don't wear nice sneakers if it just rained though; they will get muddy!

Beautiful country side. Mostly open trails, not paved. Everyone is in a great mood, even the dogs are friendly.

Fun, easy hike. A little bit of an incline at the end that makes it more fun! Partially paved, mostly gravel. On a hot day wear a hat!

Beautiful trails, beautiful views, you couldn’t ask for anything more when hiking here!

awesome trail, a little muddy but overall I would do it again

Awesome hike and the views are amazing!!!

Hiked with 3 kids (2yo,4yo,6yo) - older two walked the whole way. Started to the left; lots of doable uphill. A little difficult for 2yo due to very rocky path. First half is exposed to sun - wouldn't do this hike on a hot day. 2nd half is pleasant thru eucalyptus trees. No cyclists, but lots of dogs (on and off-leash). Took about 1.5hrs (with stops for snacks). Easy and ample parking on the side of the road and in the parking lot (with bathrooms). Decent views but nothing crazy. Lots of people on the trail.

Don't know how I missed this one. A friend lives nearby in Canyon.

This is a nice local hike that allows dogs off-leash. There's minimal to no cover, so wear sunblock and bring a hat. Also, because of the cows you will more than likely encounter your fair share of pies and flies. I would recommend this trail if you're looking for a good spot to run your pup. It is best hiked in the winter/spring months when the fields are lush and you don't have to worry about the heat.

Great trail! Was a nice mix of beautiful views on the hillside and being in the woods.

Good, solid hike. We did 3 of 4 summits, enjoyed the wildflowers. The views are nice but nothing breathtaking.

One of my favorite spots for a quick hike. Easy to get to and great fun for the Pup. Gets really busy on the weekends but it's well maintained. If your dog is a little weird with cattle you might want to keep them on a leash, as there are free roaming cows throughout the area.

Nice little hike that can get pretty crowded.

Beautiful and kid friendly.
