Hi Carolyn, Welcome back!
We're so happy you've decided to visit us again with another vacation planning question.
Up until the end of 2016, Disney's Typhoon Lagoon Water Park offered the attraction, Shark Reef. This snorkeling lagoon allowed guests the unique experience of swimming from one end to the other alongside tropical fish, stingray's and even sharks. However, this attraction closed in October of last year to make way for Typhoon Lagoon's newest thrill, Miss Adventure Falls.
Miss Adventure Falls is fun for the whole family as you all board a raft to sail the high seas on this white water voyage. It's a must-do experience on your next visit. Just select the highlighted link to read all about the new attraction that has replaced Shark Reef
Please let me know if you have any additional questions, Carolyn. My family loves the water parks, so I am here to help you plan a splash-tastic day to either Disney's Typhoon Lagoon or Disney's Blizzard Beach Water Parks.
Faith
