A sea lion haul-out is an interesting place to visit but you would not choose it as a good location for a picnic lunch. First is the constant roar. Scientist say roaring is a way that they can protect their territory when they feel threatened. This is often enough to get both humans and other animals to leave them alone. There are many sites on “YouTube” that give you an idea of the volume of the roar but nearly all of them are for “one” seal lion whereas most of the time we are viewing thirty or forty sea lions. Second is the smell. Enough said.
