About Bolon Island Tideways
Bolon Island Tideways State Scenic Corridor is a hidden gem along the Umpqua River estuary near Reedsport on the southern Oregon coast. The park sits on Bolon Island beside US 101 at the north edge of Reedsport, and a hiking trail extends half way around the island. The park protects critical estuarine habitat where freshwater from the Umpqua meets the Pacific, creating one of Oregon’s most productive ecosystems for shorebirds, herons, and osprey.
Things to Do
Walk the hiking trail that extends half way around the island. On the Umpqua River side, hundreds of double-crested cormorants have nested in the shoreline trees since 1988, each pair building a platform of sticks close to its neighbors, and the trail also gives views of the river. Oregon State Parks lists fishing and a viewpoint among the park’s features, and a marker in the park recalls Jedediah Smith’s 1828 overland trip along the Oregon coast.
Getting There
Located on Bolon Island in the Umpqua River, beside US 101 (Oregon Coast Highway) less than a mile north of downtown Reedsport in Douglas County. The park has no restrooms or potable water.
Insider Tips
Estuary magic: Bolon Island protects rare tidal wetlands along the Umpqua River estuary — one of Oregon’s most productive ecosystems. Pro tip: Visit at low tide to see shorebirds feeding on exposed mudflats. Crabbing: Dungeness crab can be caught in the adjacent estuary channels — bring a crab ring and bait (chicken works great).
Best Time to Visit
Late summer: Best crabbing and warmest weather. Fall: Shorebird migration peaks August-October. Spring: Estuary fills with juvenile salmon heading to sea. Winter: Dramatic storm watching — Oregon estuaries feel wild in winter storms.
Frequently Asked Questions
What is a tideway?
A tideway is the channel where tidal water flows in and out of an estuary. Bolon Island’s tideways support Dungeness crab, salmon, shorebirds, and harbor seals — one of Oregon’s most biodiverse zones.
Wildlife & Nature
Bolon Island Tideways — a State Scenic Corridor along the Umpqua River estuary — protects tidal mudflat and salt marsh habitat critical for migratory shorebirds. The Umpqua estuary is one of the largest on the Oregon coast, supporting commercial and recreational fisheries. Tidal mudflats may appear barren but teem with life — millions of tiny clams, worms, and crustaceans inhabit the substrate, providing food for thousands of migrating shorebirds. Dunlin, western sandpipers, and dowitchers probe the mud at low tide. Great blue herons and great egrets stalk the shallows. Harbor seals haul out on sandbanks. The estuary’s mixing of salt and fresh water creates a gradient of salinity that supports different species at each point.
Nearby Attractions
