A bad trail. A lot of small flying mosquitos or bug hanging in the air on the way, sometimes I can barely proceed among them. Bad experience.

Used to run this trail several times a week. lt’s not the most beautiful trail in the Bay Area but the views are nice in the late afternoon. The worst part is that you’re running by the sewage treatment plant on the southern end and on certain days, it’s borderline unbearable. This can be avoided by running toward the north and eastern sides and avoiding the southern end near the treatment plant. Lots of bikers can be annoying if you run along the western edge during busy periods

I was expecting to see the wetlands by looking at the pictures and it was all dry

Recycling plant and trash facility located nearby, but the smell is largely from the fact that it is a marshlands. So you will smell a lot of Sulfur and stretches of this trail. Especially in the hotter seasons.

Hi Folks, I am wondering anyone has measured the "larger" trail, sorry don't know how to describe this, I mean passing over the radar station and keep going on a curved trail then turn left, straight and then left again and back to the water gate then back to the water processing facility... :-)

Dog friendly, gravel but lots of ducks and Hawks. Also we saw a Great Blue Heron. We biked it, strong breeze but no smell or flies...maybe late Oct is better time of year.

Decent option for a walk or run at sunset - was convenient to a stay in Sunnyvale.

Walking

The trail is a gravel road and while it is a nice little hike, there's not much to look at. The best part is walking up the steep hill near the parking lot and taking in the view. Trail is not labeled so ask other people on the trail how long different loops are. Some are just a couple miles and others are longer (6+ miles).

Bird Watching

I have used this trail for biking, jogging, hiking, and birding. On the weekends it can get very crowded, but during the week there are less people and you can get better wildlife photos. These trails interconnect with the shoreline bike paths so you can go as far as you like.
