Santa Barbara lies much further south than the other four Channel Islands and is the smallest, measuring just one square mile. The island is adored by sea birds as well as campers looking for a peaceful island getaway. Sea bird colonies flourish here, and efforts to restore the overall bird habitat is a top priority. The island is one of the most important seabird nesting sites in the region. Its cliffs are home to endangered brown pelicans, three species of cormorants, three species of storm-petrels, and one of the world's largest colonies of Xantus's Murrelets. Sea lions and seals are also very popular inhabitants of Santa Barbara Island, feeding on the rich kelp forests. A special plant to look out for is the Santa Barbara Island liveforever, a rare succulent plant that grows on the island's rocky bluffs.
Island can only be reached by boat transportation.
