A paved nature trail with gentle grades winds through cottonwood and ash bottomland woods that host Hairy Woodpecker, Band-tailed Pigeon, Brown Creeper, and Black-capped Chickadee. Where the trail meets the bay, look for Osprey, scaup, Bufflehead, and cormorants. Pacific Ocean tides affect Scappoose Bay via the Columbia River estuary; at low tide sandpipers and other shorebirds feed on exposed mudflats, especially in late summer. The marine park has covered picnic areas, and a canoe/kayak dock for further exploration of Scappoose Bay.
At MP 25.9 of US Hwy 30 S of Warren (a small town between Scappoose and St. Helens), turn SE onto Old Portland Rd, then go L after crossing the railroad tracks and continue 0.3 mi to parking area for Scappoose Bay Marine Park. Nature Trail is along the waterfront to the N side of the marina store. GPS 45 49.724 N, 122 50.293 W.
