With Atlantis Submarine, your family can explore Cozumel’s famous reefs without fear of getting wet. The real navy submarine takes guests to the depths of the ocean floor, giving kids the chance to see tropical fish, coral reefs, and other marine life up close. A guide will narrate the adventure while you peer through your own peephole and everyone will be amazed at the surroundings, particularly the remains of an old shipwreck that are still visible and in decent condition. The ticket package includes a round-trip ferry ride to and from Cozumel.
