We've driven across the Dumbarton bridge which spans the San Francisco Bay many times. While speeding across we've often noticed a lovely nature reserve sitting just below the bridge. On our recent trip to San Francisco in March, we decided to pull off the road on the Silicon Valley side of the Don Edwards National Wildlife Refuge and have a little look around.
The grassy, marshy area just below the bridge is actually quite stunning. I really like how this old railroad bridge seems to be almost shimmering in the early morning mist.
After about 15 minutes wandering around, we headed back to the car for the remainder of our journey to Alameda.
