Sea Lion Caves in Yachats, Oregon, is an enormous grotto of wonder and splendour and this creation of nature is home to hundreds of sea lions. A 208ft elevator descent takes you into a dark area where an observation window allows you to watch as sea lions vie for the best seat on the rocks. This spectacular attraction is a boost to adventure tourism, and it is in this natural amphitheater that sea lions gather during fall and winter. Sea Lion Caves was established in 1932 as a privately owned bird sanctuary and wildlife preserve that allows this protected species to come and go as they please and this amazing attraction provides excellent adventure tourism. Tours take visitors close to ocean level where they can see the gigantic cavern and its wildlife inhabitants.
