My favorite places to access the Cedar River walking trail are at Cedar River Park, Renton Library, Renton Senior center, and Renton Stadium. The trail stretches for more than 5 miles and follows the Cedar river which is a great place to see birds, watch the salmon runs, catch boating views on Lake Washington, and watch small airplane take offs and landings. Even the views of Boeing are of some interest. I've spotted many mergansers, kingfisher, grebes, many duck species, great blue heron, little green heron among others. Cherry trees bloom in spring. Many picnic facilities, river access for small boats and inner tubes.
