The Oregon Dunes stretch for 40 miles along the Oregon Coast and are very popular for OHV riding. The dunes are jointly managed by the national forest service, Oregon state parks and Oregon Dunes NRA. We bypassed the dunes but stopped at the Lagoon Campground to walk/roll along the Lagoon Trail. The trail is hard packed dirt and boardwalk and is considered accessible. Wheelchair users may need assistance in several spots where the trail has deteriorated. It may be flooded in rainy weather.
The campground was empty, unusual for a weekend but I think that the other campgrounds are better for OHV dune access. The accessible campsite is very good with a wide, paved parking pad. The table has an long overhang, the fire ring has high sides, and pavement extends under both the table and the fire ring. A paved path goes to the restroom.
Some of the campsites are large enough for any RV. The trail starts in the campground. If you’re not camping and want to walk the trail you can park along the road to the west of the campground entrance where a boardwalk provides a link to the trail. Trail 43.87784, -124.14281
