Oregon Dunes
Florence
The Oregon Dunes are the largest expanse of coastal sand dunes in North America, a forty-mile sea of sand running down the coast from the Siuslaw River near Florence to the Coos River, with some dunes rising as high as 500 feet above the ocean. Walk out into them and the ordinary world drops away: no trees, no clear horizon, just wind-sculpted ridges of pale sand stretching toward the surf.
If they feel like another planet, there is a reason. These are the dunes that gave us Dune. In 1957 a journalist named Frank Herbert came to Florence to write about them, and what he saw here became the desert world of Arrakis in one of the most famous novels ever written.

The story of the Oregon Dunes
This coast is the homeland of the Coos, Siuslaw, and Lower Umpqua peoples, who lived along these rivers and estuaries for thousands of years, fishing, gathering shellfish, and hunting the wetlands behind the dunes. Their descendants today are enrolled in the Confederated Tribes of Coos, Lower Umpqua and Siuslaw Indians.
The dunes owe their fame to a book. In 1957 Frank Herbert, then a journalist, came to Florence to research an article about a government effort to tame the shifting sand by planting European beachgrass, a piece he meant to call ‘They Stopped the Moving Sands.’ The article was never published, but the idea of a landscape of living, moving dunes took hold of him. Years of research later it became Dune, published in 1965, with its desert planet Arrakis and its endless sand. Herbert had found his world on the Oregon coast.
Congress set the dunes aside as the Oregon Dunes National Recreation Area in 1972, and the Forest Service has cared for them ever since as part of the Siuslaw National Forest, more than thirty thousand acres of sand, forest, and wetland.
How the dunes formed
The sand began in the mountains. Over countless years the Coast Range eroded, and its rivers, the Siuslaw and the Umpqua among them, carried the grains down to the sea. Waves washed the sand back ashore, and the wind did the rest, pushing it inland dune by dune. Summer winds blow from the north and winter winds from the south, so the dunes are never truly still: they shift, migrate, and rebuild with the seasons. The tallest ridge, known as Banshee Hill, rises about 500 feet.
There is an irony at the heart of the place. The very beachgrass Frank Herbert came to write about, planted to hold the sand in place, has done its job too well. Introduced along this coast through much of the twentieth century, the tough European grass now locks down the foredune and is slowly smothering the open sand, so the great dunes Herbert saw are gradually shrinking. The Forest Service and local volunteers now work to pull the grass back and keep the sand on the move.
Wildlife and the tree islands
The dunes are home to the western snowy plover, a small, pale shorebird that nests in shallow scrapes right on the open sand. It was listed as threatened in 1993, and careful protection of its nesting grounds, roughly from mid-March through mid-September, has slowly brought its numbers back. During those months some stretches of beach are roped off to give the birds room, and it is worth keeping a wide berth.
Scattered across the sand are ‘tree islands,’ pockets of forest the dunes have surrounded but not yet buried. Behind the foredune lies a broad, marshy deflation plain where the wind has scooped down to the water table, now a green ribbon of ponds and shore pine. Roosevelt elk move through the wetlands and forest edges, and shorebirds work the beach.
Season by season
Summer is the season for the dunes: warm, dry days for hiking out to the sea, sandboarding the big open bowls, and riding the designated off-highway areas at the north and south ends. It is also snowy plover nesting season, so parts of the beach are closed to protect the birds.
Fall brings quieter sand and softer light, a fine time to walk the dunes without the summer crowds.
Winter is when the dunes come alive with weather. Storms drive in off the Pacific, the south wind reshapes the ridges overnight, and the whole landscape feels wild and elemental. Dress for wind and rain and you will likely have the sand to yourself.
Spring greens the deflation plain and reopens the season, as the plovers return to nest and wildflowers appear in the swales.

Things to Do Near Florence
Florence sits at the north end of the dunes, its Old Town a walkable riverfront of shops and seafood along the Siuslaw.
Jessie M. Honeyman State Park, just south of Florence, tucks two freshwater lakes among the dunes, and the John Dellenback Dunes Trail leads through some of the largest open sand out to the beach.
North up Highway 101, the Heceta Head Lighthouse and the Sea Lion Caves make an easy add-on to a day in the dunes.
