America’s largest sea caves are 11 miles north of Florence, Oregon and a year round home of Stellar sea lions. The sea lions may not always be in the cave, depending on the time of year for breeding or birthing but you could check that online with the Sea Caves to make sure the sea lions would be there for your visit.

After descending in the elevator for 208 feet, we entered the darkened cavern which is quite large. It uses the natural layout and does have a sign to warn us it could be “subject to earthquakes, erosion and landslides”! Nice! The one area for viewing has a mesh screen to prevent anything or anyone from falling but the noises are not blocked.
|The sea lions enjoy their cave
The noise was incredible! They all seem to want to be heard and the roars, grumbles and growls are a constant loud noise above the splashing waves coming into the caves. Springtime turned out to be a perfect time and there were hundreds in the caves for our visit.
|Hundreds of sea lions visit the cave
These beautiful sea lions were all over the rocks with some wiggling for the same space and pushing another away. The cave is lit up only with the daylight coming in through the mouth of the caves so plenty of them cannot be seen from our vantage point but watching those we could see was fascinating.
|Lots of movement
The Stellar, also called the Northern Sea Lion is the biggest of the seven species of sea lions. The female’s average length is 2.5 m (8.2’) and 263 kg (580 lbs). The average male is 3 m (9.8’) and 544 kg (1199 lbs) but are known to be as large as 3.3 m (11’) and 1134 kg (2500 lbs).
|The sea lions are very vocal
They are found in Alaska, Japan, British Columbia, Washington and Oregon, sometimes down into California. The Stellar are often confused with others, especially the California sea lion, even though there are physical differences between all species of sea lions.
|A nursing mother
Most seafood is their diet. They do not chew but swallow whole so that sounds interesting, who knows what goes on inside their stomach! Young pups can nurse for as long as 3 years. Adult males eat 5-6 % of their body weight daily and young ones need twice that amount.
|Heceta Head Lighthouse in distance
Another viewpoint from within the caverns of the sea lion caves looks north to the Heceta Head Lighthouse, circa 1894 and is the brightest light on the Oregon coast. The beam can be seen 33 km (21 mi) out to sea.
