Catalina Island: Day Trip with Undersea Sub Expedition

About

See Catalina's marine life up close aboard a semi-submersible vessel with a climate-controlled cabin. You'll see garibaldi, spotted calico bass, urchins, rockfish, and bat rays as they feed just outside your window. The tour takes you five feet underwater for a clear view of these undersea creatures. Combine the **Undersea Sub Expedition** with the **Discover Avalon tour** for a complete land and sea adventure. The Avalon tour covers seven and a half miles and offers a detailed history of Santa Catalina Island. Don't forget to bring your camera!
