Located at the head of Hood Canal, Theler Wetlands consists of more than 3 miles of accessible walking trails within 139 acres of protected salt marsh and estuary wetlands. If they’re open, you and your family can discover the displays and hands-on exhibits that teach more about the wetlands ecosystem.

From the visitor center, walk along the River Estuary Trail, which follows an old dike for about 0.5 mile. At the first junction, go right to explore the recently restored saltwater estuary. Watch for red-winged blackbirds, kingfishers, herons, Canada geese and other waterfowl.

The trail continues for about half a mile, passing the Pacific Northwest Salmon Center before rejoining the River Estuary Trail. Turn right, passing the picnic area and restroom, to a series of boardwalks that lead to a junction at 1.25 miles, where a viewing platform overlooks the Union River.

Before returning to the parking lot, take the quarter-mile South Tidal Marsh Trail for views of Hood Canal and the Olympic Mountains. Also consider exploring the Sweetwater Creek and Alder Creek Trails, both of which make nice quarter-mile loops.
