The parking lot only had a few cars when I arrived around 8am. There are bathrooms and water here if you need it. We crossed the street and then went through an entrance gate to start the hike proper.

Bridge at the start of the trail

There are essentially two parts to this hike. We started off to the right, which is a short 0.3 mile path to an observation platform. The trail is hard-packed gravel raised above the marsh. There are lots of various birds in the area, and I stopped to take pictures of an egret here. There were also a few boats in Smith Slough.

Various birds at the marsh

We soon reached the observation platform. After taking in the views, we turned around and headed back the way we came. Then we started the longer path (the left fork at the beginning), which leads to a second observation path. Both observation platforms are on Inner Bair Island (there are actually 3 islands: Inner, Middle, and Outer).

The freeway is visible on your left, with the marsh on your right. At times there were large numbers of birds visible in the marsh. This longer path is about 1.7 miles to the observation platform.

You'll see small airplanes flying into nearby San Carlos airport as you continue on the trail. The observation platform has another view of Smith Slough. After taking in the views, we returned the way we came, back to the trailhead and back to the parking lot.

There's not a lot to this hike, but if you decide to go, I'd recommend going as early in the morning as you can while it's still peaceful and you can enjoy all the birds without too much traffic noise or sun (there's no shade at all).
