I am wondering if other familiies with children have snorkeled around Waterlemon Cay. We have been to St. John once before when our kids were 10 and 7. We swam from the end of the trail over to Waterlemon Cay, but I was afraid to go around the cay with the kids. Also, no one but me had fins. Next summer, the kids will be 12 and 9 and are fairly good swimmers. If we all have fins this time, I am wondering if we can make the snorkel all the way around the cay. Has anyone with kids about this age done it before? Also, how can you tell if there is a strong current or not? Or do you not know until you are in the water?
