The Oregon coast is one of my favorite places to visit. The sunsets are amazing, the beaches go on forever, and the rustic rock formations are unbelievable. The Oregon Coast is a coastal region of the U.S. state of Oregon. The Pacific Ocean borders it to the west and the Oregon Coast Range to the east, and stretches approximately 362 miles from the California state border in the south to the Columbia River in the north. The region is not a specific geological, environmental, or political entity, and includes the Columbia River Estuary.
