Small islands appear in the middle of the slough. The marshes get wider, cut by small channels and sloughs. On the opposite bank of Belmont Slough is the unpaved Bay Trail along Redwood Shores. At 2.2 miles, the trail passes the end of the long lagoon. A short connector path leads inland to the bank of the Foster City Lagoon at Sea Cloud Park.
Houses line the lagoon to the right.
This is one end of the long, winding lagoon, whose other end is near the San Mateo-Hayward Bridge. The Bay Trail continues to follow Belmont Slough next to a row of condos. It makes an S-turn to the right, then left. At 2.4 miles is a sign at the edge of the marsh identifying it as the Belmont Slough Wildlife Refuge. A narrow dirt footpath leads into the marsh and across a wooden plank bridge.
