My Mom and I went on the Sea Trek Adventure in April. We didn't know we would have to put on a wetsuit but it was totally worth it!!! It feels like you are scuba diving with so many sea creatures surrounding you. It was peaceful and exciting at the same time with the gentle manta rays gliding over your head and sea turtles swimming up to peer into your helmet! We even got to pet the silky belly of a GIANT Manta Ray - what an unforgettable experience!!!
