After reading about all of the different stinging jellyfish, sponges, rays, etc on the National Park website, we are wondering where are the safest places to snorkel so that we may not encounter these animals. (I know it's the ocean and some marine animals are more mobile than others.) In St. Martin, we snorkel right off of Orient and don't really worry about it except a few barracuda. Any ideas would be appreciated. 21 days and counting.
