We had been camping at Tugman State Park, 10 miles south of Reedsport, Oregon. We explored the beautiful Umpqua River valley down to the boat docks at Winchester Bay. Lovely cloudy skies and cool daytime temperatures (low 70'sF). Eel lake was quite lovely.
We hiked up the huge sand dunes along South Jetty Road, below Florence, Oregon, at the Siuslaw River terminus at the sea. West of the dunes was the beach and breaking shore waves. Lots of shells. We were the only persons visiting the beach at that time.
The sand dunes by the ocean in Oregeon are the largest ocean dunes in the USA. They stretch for 60 miles from Florence to below Coos Bay, Oregon, along the Central Oregon Coast. At some points the dunes are 20 miles wide.
