Top Catalina Island Submarine Tours

See what lives in the Pacific waters surrounding Catalina Island on a 45-minute underwater cruise. As you sit comfortably in a climate-controlled cabin on board a large boat, you'll glide five feet (1.5 meters) below the surface to look for marine life in their natural habitat out of your own porthole. Along the way, listen to live commentary from a guide.

Discover the underwater world of Catalina Island during a 45-minute ride on a semi-submarine. The semi-sub allows you to view the marine life of Avalon Bay as you dive six feet (two meters) below the surface at Lovers' Cove. Stay dry as you get a close look at fish feeding around the submarine, then take in views of the island from your vessel's top deck during the return journey to Avalon.
