At just under 20 acres, Dumas Bay Wildlife Sanctuary is a hidden treasure on the Puget Sound. Located on the northern slope of Federal Way, a short and broad gravel path shaded by young bigleaf maples leads down to the Dumas Bay beach and cove overlooking the sound's east passage.
Unlike nearby Dash Point State Park, the beach itself is rarely visited, making it an ideal location to relax in solitude. It is also a great place to catch some of the local flora and fauna. The wetlands and cattails attract red-winged blackbirds and various species of waterfowl, and the sanctuary is home to one of the largest breeding colonies of great blue heron in the Tacoma and Federal Way area. Keep your distance, but visiting between the beginning of February (breeding season) and the end of April (hatching period) will give you the best opportunity to catch a glimpse of these long-legged birds.
Note: Dogs and pets are permitted within the sanctuary, but not on the beach. Campfires are also prohibited on the beach.
