Part of the Siuslaw National Forest, the Oregon Dunes cover 40 miles along the coast, North America's largest coastal dunes. There are many ways to explore this dramatic natural wonder: by air, foot or off-highway vehicle (OHV). Recreational opportunities include quiet nature trails through vegetation teeming with wildlife, birding, beachcombing, fishing, sandboarding or sand sledding, stargazing and camping. Dune buggy rides with a professional guide are encouraged
