Saint Thomas Snorkeling Tour with Castaway Girl! The Castaway Girl had a super fun crew who kept the action going with music and drinks. We started off with a 3 mile trip to Buck Island/Turtle Cove. After snorkeling we took off to Honeymoon Beach at Water Island where we had a catered lunch and more snorkeling. On the way home the Castaway became a dance floor. Unfortunately couldn't post any of the footage because of the background music. Highly recommend the excursion by Castaway Girl which we took via our Royal Caribbean cruise. Music by Epidemic Sound.
