PIER 39 commemorates the 20th anniversary of the sea lions’ arrival at PIER 39. Through the years, California sea lions have taken over PIER 39’s K-Dock to the delight of spectators. Each January, these marine mammals return in droves for herring season in San Francisco Bay. In celebration of the sea lion’s anniversary, visitors can watch the sea lions in close proximity, talk with knowledgeable Marine Mammal Center docents about these amazing animals and stop by the Whale Bus for a complete educational experience. PIER 39 invites visitors to see for themselves why K-Dock in PIER 39’s West Marina, has been declared a “Watchable Wildlife” viewing area by the California Watchable Wildlife Project. Come watch Friday January 15, 2010 from 10:00 a.m. to 5:00 p.m.
