When in St.Thomas take the Red Hook ferry over to St. John's for some great snorkeling. Once at St. Johns, you can get a taxi over to Trunk Bay where they have a marked underwater trail. You can also rent snorkeling equipment and they have changing facilities. Well worth going, enjoy.
new guy here again.
can a person take snorkling lessons on board? I'm a flatlander, never seen an ocean, and would love to experience more water than a bathtub! I'm sure there is some skill to this; they just don't throw people in the water and say " SNORKLE!"
I think your best bet is to do one of the ship excersions that is a snorkeling tour.
They will give you a lesson and once you get the hang of it, you'll love it I'm sure.
Its really easy and I always wear a floatie thing, I can then stay out there for hours, its really a lot of fun and so much to see, give it a try:-) There even may be a snorkeling lesson on boards the ship, check out in the daily activities.
