From the John Dellenback Dunes Trailhead off of U.S. Highway 101, immediately cross a wooden bridge over slow-moving Eel Creek. After a few hundred feet, come to a junction. Heading left (clockwise) at this junction, the trail starts climbing up into the Oregon Dunes. A series of interpretive signs describe the geological and ecological significance of these dune features.
The next 0.25 miles are entirely on sand, and running can be difficult. Through this stretch, keep a careful eye to stay on the trail, since the dunes negate the presence of an overt dirt "trail". Blue posts are staked along the way as a guide.
At about 0.4 miles from the trailhead, reach another junction with the John Dellenback Dunes Trail (#1339)
. Turn left here to embark across the dunes to the ocean; turn right (downhill and into the woods) to finish the Interpretive Loop. After descending the hill, cross a paved road. This is the Siuslaw National Forest's Eel Creek Campground.
The remainder of the trail skirts the outer edge of the campground. Return back over the same bridge spanning Eel Creek to reach the trailhead where the run began.
Many sections of the beach area are preserved for snowy plover nesting sites. Be aware of national forest regulations regarding these preserves.
