There's a reason why Catalina island draws in so many diving enthusiasts — on this private catamaran cruise, you'll find out exactly why. Heading across on your very own catamaran, you'll have ample chance to don your snorkelling mask to see the impressive coral reefs and marine life at the Wall. And if you don't fancy making a splash, there's plenty of other things to see and do, from rock formations to kicking back on the beach. There's also a tasty lunch and an open bar included.
