Don Edwards San Francisco Bay National Wildlife Refuge

Beautiful, accessible, uncrowded. Lots of sea and shore birds at the right times-cormorants, great egrets, snowy egrets, sandpipers, shovelers and other ducks (and many I don't know). Lovely flowers at all times of the year, but especially in the spring. Good for a quick semi-challenging dog walk or a longer run if you want to go out into the bay on the dog-free paths.

Awesome park free parking! When you come down the wooden bridge thing if you turn right... beware its a 2 hour walk bur don't stress it loops and goes full circle my smart watch said it's like 7 miles. Just stay on the beaten path and there's no way to get lost also for being in one of the most populated areas in america I didn't see anything but birds not a person around for miles! Once you reach the old dredge your about a 1/3rd of the way done enjoy!

A great place to walk, hike, bike, learn about wildlife, or just chill and enjoy the nature. Great views overlooking the water and Dumbarton Bridge.

It's a nice place with a great view perfect for a pleasant day. There are few short trails that you can walk on alongside the lake

Great place to walk with a nice breeze. You can do long or short walks. Trails are in great condition and most are very easy.
