The Siltcoos River is a 3-mile (4.8 km) stream on the central coast of Oregon. It begins at Siltcoos Lake and meanders generally west to the Pacific Ocean. It is located about 8 miles (13 km) south of Florence and 13 miles (21 km) north of Reedsport. The river and canoe trail passes through the Siuslaw National Forest and the sand dunes of Oregon Dunes National Recreation Area. The Oregon Dunes are a unique area of windswept sand that is the result of millions of years of wind and rain erosion. These are the largest expanse of coastal sand dunes in North America, and some dunes rise to 500 feet (150 m). Learn more about the canoe trail here.
