The Oregon Coast, Oregon For one of the most awe-inspiring road trips in America, follow U.S. Route 101 and the western edge of the continent from north to south. Begin at the northern outpost of Astoria, the richly historic city where the Columbia River flows into the Pacific. At Cannon Beach, northern Oregon’s most beautiful seaside village, sandy beaches stretch for miles, interrupted by massive basalt sea stacks such as the iconic 235-foot Haystack Rock. Route 101 stays close to the coast, traversing river valleys and climbing up over the flanks of mountains that reach down to the Pacific. The view from Neahkahnie Mountain, where the road edges around 700-foot cliffs that drop into the surging Pacific, is of wide-open seascape—on a clear day, you can see for 50 miles.
