Historical Context: From Discovery to Tourist Attraction
The story of Sea Lion Caves began in 1880 when Captain William Cox discovered this massive cavern while navigating the Pacific Coast. Captivated by its size and the presence of sea lions, Cox purchased the land in 1887 from the State of Oregon. The property remained in his family until 1926 when R. E. Clanton acquired it with a vision to transform it into a public attraction. By 1930, Clanton had partnered with J. G. Houghton and J. E. Jacobson to develop the site. Together, they hand-excavated a 1,500-foot trail into the cliff face and built a 135-step wooden tower leading to the cave’s north entrance. Their efforts culminated in August 1932 when Sea Lion Caves officially opened to the public.
The early years saw steady growth in visitors, especially after U.S. Route 101 was completed past the site. Initially a gravel road with multiple ferry crossings until 1937, it became a key route for travelers. A traffic light was installed to manage visitor flow until World War II halted recreational travel in 1942. In 1934, Clanton withdrew from the partnership, and R. A. Saubert became a part owner. The business was operated by three families until 2006 when it passed to the Saubert and Jacobson families.
A significant milestone came in 1961 when the Otis Elevator Company installed an elevator to transport visitors directly to the cave floor. This replaced the arduous climb and could carry 23 passengers at a time. The original elevator was replaced in 2016 with a new one to ensure continued safe access.

Geological Formation: A 25-Million-Year Legacy
Sea Lion Caves isn’t just a haven for wildlife—it’s also a geological marvel shaped over millions of years. The cave system began forming approximately 25 million years ago when volcanic activity created layers of basalt rock along what is now the Oregon Coast. Over time, the relentless action of Pacific Ocean waves eroded these softer rock layers, carving out the vast chambers and passages that make up the cave today.
The main cavern is immense: its floor spans about 2 acres (approximately 87,120 square feet), and its vaulted ceiling soars to 125 feet—equivalent to a 12-story building. This makes it not only America’s largest sea cave but also one of the largest in the world. The cave stretches roughly 1,315 feet long (including its passages), roughly the length of four football fields laid end-to-end.
Access to this geological wonder is through a gift shop building perched high above sea level. From there, visitors descend via an elevator that travels 208 feet down to the cave floor. The cave system features multiple entrances: the main cavern opens directly to the ocean, allowing waves to wash in continuously; a low passage to the south floods at high tide; and a northern entrance about 50 feet above sea level offers an elevated observation point with panoramic views of the entire cave system.
The geological significance of Sea Lion Caves extends beyond its size—it’s part of Oregon’s rich coastal landscape where ancient volcanic activity and erosion have sculpted breathtaking formations over eons.
Wildlife Wonders: Steller Sea Lions and Beyond
The star attractions of Sea Lion Caves are undoubtedly the Steller sea lions, one of nature’s most impressive marine mammals. These creatures are not only the largest of all sea lions but also among the largest pinnipeds (seals and sea lions). Adult males can grow up to 11 feet long and weigh nearly 2,500 pounds—larger than most grizzly bears—while females are smaller but still formidable at up to 9 feet long and 1,000 pounds. Their light tan to reddish-brown fur and distinctive barking calls make them unmistakable residents of this wild habitat.

Steller sea lions are year-round residents of Sea Lion Caves, though their numbers inside can vary by season. During fall and winter, they often gather in larger numbers within the cave for shelter from harsh weather conditions. In spring and summer, many move outside to nearby rock ledges for breeding and birthing activities. However, some always remain inside, providing visitors with an unforgettable experience regardless of timing.
Beyond sea lions, Sea Lion Caves is also home to a variety of other wildlife due to its status as a bird sanctuary. Visitors may spot common coastal birds such as gulls and cormorants nesting on nearby cliffs or soaring above the waves. Occasionally, harbor seals or other marine mammals can be seen in surrounding waters. This diversity underscores why Sea Lion Caves is such a vital part of Oregon’s Cape Perpetua Marine Reserve—a protected area dedicated to preserving marine ecosystems.
