The Sea Lion Caves is America's largest sea cave as identified by the Guiness Book of World Records. It is the year round home of the Steller Sea Lion. The Stellar sea lion, also known as the northern sea lion, is the largest member of the sea lion family. You can see these majestic beauties in their natural habitat dwelling in the formation of the cavern that began about 25 million years ago. Am It now soars to the height of a 12- story building and stretched the length of a football field. Sea lions aren't the only wild animal you will see there, the natural amphitheater is also the home to  other marine life and shore creatures! 

The cavern walls are painted with natural mineral stains like Lichens, and algae that create colorful greens, pinks, purples, tans, and reds that form on the rough surfaces. the sea level portion of this cave and sea cliff rocks just outside the cave have become, over the centuries, the only known mainland rookery or "breeding area" of the Steller Sea Lion, and to lesser extent, the California sea lion. The Cave vicinity is home to several other animals including bats, pigeon guillemots, cormorants, gulls, orcas, gray whales, humpback whales, harbor seals, California sea lions, bald eagles, mountain lions, black bear, elk, deer, chipmunks, gray squirrels, owls, common murre, tufted puffin, marbled murrelet, black oystercatcher, anklets, sandpiper, dunlin, whimbrel, snowy plover, osprey, killdeer, and numerous ducks and geese. Many seabird species are endemic and found nowhere else, except along the Oregon Coast.
