We've been taking curious Catalina visitors on journeys of discovery into Lover's Cove Marine Preserve for nearly a century. While the vessels have evolved over the years, the unique experience of being drawn in to an undersea wonderland remains the same. Meet your captain at Float B on the Green Pleasure Pier that extends into Avalon Harbour, directly offshore from Catalina Avenue. Once aboard the MoonStone, you will be able to see the bottom of the sea! You’ll see a variety of colourful fish and other sea life as you cruise through what many consider to be one of the healthiest marine environments in the world.
