Great for: Birds, water systems, nature Walden Ponds and Sawhill Ponds
There are some 24 ponds between these two preserves, which are located a half-mile apart in northeast Boulder, and they are teaming with birds. Sawhill Ponds even has strategically located bird blinds for viewers. And near the Walden Ponds parking area, a walkway at Cottonwood Marsh gives visitors an inside look at tree swallows in nest boxes.
