Gorgeous! A bit muddy. Not many people. Dogs enjoyed off leash.

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.

Great bike ride. The path is relatively smooth and goes under all of the roads and highways. If you want to do a little extra, take a left when you reach the end and loop back through Coyote hills. There is about a mile along the sliver of land that takes you back to Coyote Hills that is rocky, so don't take that path if your tires aren't cut out for it.

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