Just off the coast of Southern California, lovely Catalina Island offers endless adventures on both land and sea. Snorkel the clear waters or venture out on a glass-bottom boat tour to view the colorful marine life and sunken shipwrecks. Equally scenic vistas await you on a hiking, biking or zip-lining excursion through the island’s grasslands and woodlands. Be sure to take a behind-the-scenes tour of the Catalina Casino. Perched along the harbor, this spectacular entertainment venue has been the center of the island’s cultural scene since it opened in 1929.
