Driving from Washington, to San Diego, California, is a classic American road trip and, is cross-country, albeit north to south rather than east to west. Good thing you have to taken is traveling south, because it makes pulling off onto the scenic overlooks that much easier. Starting at the northwest tip of the United States at Olympic National Park, and remaining within sight of the ocean almost all the way south to the Mexican border.
Olympic National Park was the most impressive scenic spot during the trip. From downtown Seattle, we can take the ferry to Bainbridge Island and can drive all the way west to Port Angeles. Upon 1,500-mile, mostly two-lane route takes in everything from temperate rainforest to near-desert. Most of the Pacific Coast is in the public domain, freely if not always easily accessible, and protected from development within national, state, and local parks, which provide habitat for some rare creatures as mountain lions, condors, and gray whales.
The quickest way to San Diego from Seattle is on Interstate 5, which runs parallel to the Pacific coast but never touches within sight of it, connecting the two cities along a 1,250-mile stretch of blacktop with mostly bland scenery when compared to the coastal route.The phenomenally beautiful coastline of Northern California is rivaled only by the incredible coast of Big Sur farther south, which stretch the beachfronts of Southern California. The land of palm trees, beach boys, and surfer girls of popular lore does exist, though only in the southernmost quarter of the state.
Certainly not least are the energizing cities ,Seattle in the north, San Francisco in the middle, and Los Angeles and San Diego to the south,which serve as gateways to the landscapes in between them.If you really want to enjoy your trip from Washington to San Diego, you should budget at least three days and be prepared to drive a lot.
