South Oregon Coast Sea Stacks
Isolated outcrops of rock standing in the ocean are called sea stacks, they are remnants of rocky headlands that were eroded by wave action. You can see them along the Oregon coast at Myers Creek, Bandon, and Gold Beach. Arches are bridges of rock left above openings eroded in sea cliffs by waves. These are visible at Myers Creek and Arch Rock, south of the Pistol River bridge.
A series of unnamed sea stacks adorn the shores of Pistol River State Scenic Viewpoint near Gold Beach on the southern coast, making it one of the more beautiful roadside beaches in the state. You can find the sea stacks at what's known as Pistol River Middle, where there's a parking area right in front of the rocks.

A gorgeous rock formation off the coast of Harris Beach State Park, Goat Island is recognizable by its sweeping top and imposing south face. The 21-acre rock is considered the largest island off the Oregon coast, and is also home to a national wildlife refuge to protect nesting sea birds. You can see it from Harris Beach or get another angle at nearby Rainbow Rock viewpoint.
