After millions of years of erosion, the twin sea stacks of Twin Rocks were connected at one point to form a single structure. Prior to 1925 the Twin Rocks were called the "Profile Rocks" until they changed names due to a conflict with another set of profile rocks in the region. If you look closely, you can see a sea dragon, Indian, princess or Lochness monster.The pinnacle is 88' high and the hole is 35' across. You can actually fly a helicopter between the two formations. When viewed from above, the rocks are in affect a narrow wedge-shape perched on top of a rocky island.

The Pronto Pup was invented by the husband and wife team of George and Versa Boyington in the late 1930s in Rockaway Beach, OR. The Boyingtons ran a small hot dog stand on the beach, selling the dogs to tourists and locals alike. When the rain came and ruined the buns, making them soggy and inedible, George Boyington came up with the idea of cooking a "bun" as needed. He created a pancake batter based mix and the duo came up with the formula used today.

Green flashes and green rays are optical phenomena that occur shortly after sunset or before sunrise, when a green spot is visible, usually for no more than a second or two, above the sun, or a green ray shoots up from the sunset point. The reason for a green flash lies in refraction of light (as in a prism) in the atmosphere: light moves more slowly in the lower, denser air than in the thinner air above, so sunlight rays follow paths that curve slightly, in the same direction as the curvature of the Earth.

A few giant trees remain in Oregon's coastal forests. One such area to see Giant Cedars is in Rockaway Beach's 45-acre Old-Growth Cedar Wetlands Preserve. The mammoth Western Red Cedar at the end of the trail in Rockaway Beach ranks among Oregon's biggest trees in circumference, at 49 feet. A trail leads less than a mile through a boggy area of giant trees, ending at Rockaway's biggest of all, where a decked boardwalk platform, compliments of the Citizen Sub Committee for the City. Mrs. Height Miller granted the beautiful sanctuary to the Nature Conservancy of Oregon recording in her deed that it was to be used for educational and scientific purposes only. The Conservancy in turn has granted it to the City of Rockaway Beach. In order to honor the deed, the City has plans to keep one entrance off of Hwy 101. This will be the only entrance used to reduce impact as she wished and still allow visitors to walk a looped trail to see the magnificent old growth. The trail will enter and exit at that same location on Hwy 101 and is the current project before the Nature Preserve and Waterways Committee.

Glass floats, glass fishing floats, or Japanese glass fishing floats are popular collectors' items. They were once used by fishermen in many parts of the world to keep their nets afloat. These glass floats are no longer being used by fisherman, but many of them are still afloat in the world's oceans, primarily in the Pacific. Today most of the glass floats remaining in the ocean are stuck in a circular pattern of ocean currents in the North Pacific. Occasionally storms or certain tidal conditions will break some floats from this circular pattern and bring them ashore. It is estimated that floats must be a minimum of 7–10 years old before washing up on beaches in the Pacific Northwest.

After the end of World War I in 1918, a popular attraction in Rockaway Beach was to take a joy ride in WWI airplanes. The bi-planes would use the sand on Rockaway Beach as a landing strip and sell tickets to passengers wanting to experience the thrill of flight. This went on until one day a plane struck a nun walking on the beach. It's not known if the nun survived, but the plane rides ceased immediately after the incident.
