We took our boat from Grenada to St. Lucia. I would say the good snorkeling/diving wasn't quite as easily found on that trip as in Belize or the BVI (the only 2 other places we've sailed so far, not by far the only places we've dove). Had hoped to experience some stronger winds and waves as that is the reputation the area has, but many times we were on flat water with the motors running. It was quite interesting experiences to be checking in and out of all the countries/islands between Grenada and St. Lucia.. interesting for sure! I know we're booked St. Lucia this fall 2 weeks.. and haven't really decided which direction we'll go.
