Not many Bay Area residents know that they have a volcano nearby but Sibley Volcanic Regional Preserve is home to one! This volcano, Round Top, dates to about 10 million years ago and is the source of all the volcanic rock in the park. The unstaffed visitor center provides a thorough geological history of the park through display panels and specimens. Park Hours: 7am to 6pm Nov-Feb; 7am to 10pm Mar-Oct Fees: No fees

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.

Decent amount of people and unleashed dog. Very pretty though, a few longer trail options. Once it rains I bet it's very cool along the little river bed.

Fantastic course. Saw the labyrinth, beautiful eastern views, then from desert down into the thicket of the forest. Saw lava rocks. Excellent.

Hot Hot Hot! Trails are not marked very well; I ended up going to far down and had to walk up a steep road with the dogs that seemed to never end. We got our exercise fersure but bring lots of water; I almost fainted. Better fall or spring trail.

Hot! This is a nice walk but beware if it's a hot day, no shade

If you get off the main loop, there are lots of nice surprises like labyrinths and hobbit forests. Easy hike but lots of variety.

Wonderful views all along the trail! Great hike to have the dog off leash :)
