Catalina Island: Day Trip with Undersea Sub Expedition
About this experience
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!

HMBotel notes for choosing your ticket
Compare the inclusions above with your plans: admission, a guided visit and a combination ticket may cover different services. The venue name alone is not enough to compare them.
Check the meeting point and arrival instructions before adding another activity. The displayed duration describes the activity; plan travel from your hotel and your return separately.
Booking and payment take place with Tiqets. On that final page, confirm the date, participants, visit language, final price and cancellation rules; an indicative HMBotel price is not a guarantee of availability.
