Belmont Slough is picturesque, with salt marshes filled with cordgrass and pickleweed. Along this lovely path, you can see plenty of herons and shorebirds, adding to the beauty of this part of the estuary.

The paved Foster City Levee Pedway follows the bank of Seal Slough on a scenic tour of the river's lakeshore developments. By definition, the slough is somewhere between a lake and a river; it looks like a river and feeds into San Francisco Bay, but has little to no current.

Water Dog Lake, also known as the John Brooks Memorial Open Space, is located in Belmont, California. The park features a network of trails open for hiking and mountain biking, but dogs must be kept on leash at all times.

This lake is actually an obstructed stream, once dammed up to provide water to nearby Belmont. Now it's a fantastic recreation site, with several loops of trails that are good for hiking, running and biking.

Watch out for poison oak when hiking around Water Dog Lake! As long as you avoid the three-leaved menace, you'll find some nice dirt trails, and welcome shade from oak trees, around this lake.
