Oregon Coast Bikeway and Siletz River Loop

This route combines two distinct experiences. The Oregon Coast Bikeway section is generally difficult, featuring frequent ups and downs, significant elevation gains, and sections with tight curves and shared roadways, including challenging tunnels. In contrast, the Siletz River area offers a mellower ride, with parts described as 'easy, mellow riding' through riparian woods, and 'basically flat' for the first 14 miles from Highway 101 to the town of Siletz. However, venturing further inland on certain county roads can introduce significant climbs and mixed surfaces.

The most favorable conditions for cycling this route are typically from late August to early October. During this period, you can expect more moderate temperatures, prevailing north winds (beneficial if riding north to south on the coast), lower precipitation, and reduced traffic compared to peak summer months.

The route offers diverse scenery. Along the Oregon Coast Bikeway, you'll experience stunning ocean views, rugged cliffs, and charming coastal towns. The Siletz River section provides a change of pace with lovely, unpopulated riparian woods, views of a classic Oregon coastal river, and glimpses of small towns. Notable highlights on this specific route include the Boiler Bay State Scenic Viewpoint, Yaquina Bay Road, and Siletz River Highway.
