Nice flat trail. Pretty good views of San Pablo Bay. Only encountered one other hiker on a Sunday, so it’s a good place for solitude.

Nice, easy going walk. Area is well maintained and trail is wide enough so you can continue to socially distance while walking by others. Weather was nice but there is no shade so be prepared in warmer weather.

not the way it used to be totally different but it was a great walk exploring what is still out there...like the now desolate Mare Island golf course.

We had the trail all to ourselves!! Not a single person out here! When we returned to the parking lot there was 1 other car but never saw the person driving it. Beautiful Monday at Mare Island!
