The Green River Natural Resources Area (GRNRA), just east of Van Doren's Landing Park in Kent, is a hidden gem along the Green River Trail, especially for birders, cyclists, and walkers who enjoy a mix of wetland, prairie, and river views all in one place. Originally developed as a stormwater treatment facility, the area now serves a dual purpose: it filters urban runoff and provides essential habitat for wildlife. The result is a 304-acre patchwork of restored wetlands, ponds, and native plantings that feel far more wild than their suburban surroundings suggest. From the trail, especially near Van Doren’s Landing, you’ll see viewing platforms and side paths leading into the heart of the GRNRA. Expect to spot herons, ducks, red-winged blackbirds, and—if you're lucky—bald eagles or osprey. Interpretive signs explain the ecology and the city’s innovative use of the land. It’s also a great stop for a break if you’re riding—plenty of benches and low-traffic paths make it easy to linger. Let me know if you want a good loop or spur trail that includes both the Green River Trail and the GRNRA.
