Located north and south of Reedsport Oregon, and southwest of Eugene on the Oregon coast, the Oregon Dunes National Recreational Area is well known for its sand dunes (shocking, we know!), OHV (off highway vehicles) and horseback riding trails...but hiking, fishing, camping and other oceanic recreational activities also thrive here in the Oregon Dunes. Map shows the areas open or closed to motorized vehicles, as well as campgrounds and suggested trails.
