The luxury catamaran makes two stops along Seven Mile Beach for passenger pickups; make sure to check in at the beach front dive shop before your departure.
Wade in to the water and climb the few steps to the waiting catamaran, then sail down the coast of Seven Mile Beach. The boat is headed for two snorkel stops, the first at the USS Kittiwake, a submarine that sunk off the coast of Grand Cayman in 2011. Once the boat anchors nearby, get help with your provided snorkel gear and jump in. You can swim right over top the huge submarine, sunk in 60 feet (18 meters) of water, the top of which is just 15 feet (4.5 meters) of water. You'll see an unusual ecosystem of underwater plants and animals taking over the hulking ship.
Stop next at a coral reef, where you'll dive in again for another spin in the clear, shallow water. Get some inside info from your guides on the types of living coral and fish you might see.
Climb back on boat for your ride back, and unwind with a drink from the cash bar on the way back to the beach. Soak up the sun and scenery before getting dropped off back at the beach.
