The mantas were graceful, peaceful, giant, gentle creatures. I had a friend who said I absolutely had to do this and she was right. It doesn't matter if you are a good swimmer, or even comfortable in the water; Sea Quest takes care of everything! It is a really short boat ride, a tiny bit of swimming is required but you have a pool noodle. Many of the people in our group were older and they had no problems. This was a unique experience to be with some of the best mother nature has to offer. My final comment is our boat Captain, Ryan, and the whole crew were top-notch and they were all very knowledgeable about the mantas.
