Reach Sheriff training center off of Sandbar Circle from American River Drive. Think the water treatment plant is still being used, more like a sewer treatment plant ( smells like it at times, too.)
Walk East From the levee gate down the bike trail will get ya to Arden Pond, and a great area to view lots of wildlife from coyotes and fox, to owls and hawks...and a buncha' snakes!! Some great fishin, too.
Guess I'm "driftin 'a bit but this exact area is my favorite hangout!! Best part is..just walk in, no charge!!!.
